 * });
 * @param options - Object with the following properties:
 * @param options.buffer - The buffer containing height data.
 * @param options.width - The width (longitude direction) of the heightmap, in samples.
 * @param options.height - The height (latitude direction) of the heightmap, in samples.
 * @param [options.childTileMask = 15] - A bit mask indicating which of this tile's four children exist.
 *                 If a child's bit is set, geometry will be requested for that tile as well when it
 *                 is needed.  If the bit is cleared, the child tile is not requested and geometry is
 *                 instead upsampled from the parent.  The bit values are as follows:

 *                  <tr><td>3</td><td>8</td><td>Northeast</td></tr>
 *                 </table>
 * @param [options.waterMask] - The water mask included in this terrain data, if any.  A water mask is a square
 *                     Uint8Array or image where a value of 255 indicates water and a value of 0 indicates land.
 *                     Values in between 0 and 255 are allowed as well to smoothly blend between land and water.
 * @param [options.structure] - An object describing the structure of the height data.
 * @param [options.structure.heightScale = 1.0] - The factor by which to multiply height samples in order to obtain
 *                 the height above the heightOffset, in meters.  The heightOffset is added to the resulting
 *                 height after multiplying by the scale.
 * @param [options.structure.heightOffset = 0.0] - The offset to add to the scaled height to obtain the final
 *                 height in meters.  The offset is added after the height sample is multiplied by the
 *                 heightScale.
 * @param [options.structure.elementsPerHeight = 1] - The number of elements in the buffer that make up a single height
 *                 sample.  This is usually 1, indicating that each element is a separate height sample.  If
 *                 it is greater than 1, that number of elements together form the height sample, which is
 *                 computed according to the structure.elementMultiplier and structure.isBigEndian properties.
 * @param [options.structure.stride = 1] - The number of elements to skip to get from the first element of
 *                 one height to the first element of the next height.
 * @param [options.structure.elementMultiplier = 256.0] - The multiplier used to compute the height value when the
 *                 stride property is greater than 1.  For example, if the stride is 4 and the strideMultiplier
 *                 is 256, the height is computed as follows:
 *                 `height = buffer[index] + buffer[index + 1] * 256 + buffer[index + 2] * 256 * 256 + buffer[index + 3] * 256 * 256 * 256`
 *                 This is assuming that the isBigEndian property is false.  If it is true, the order of the
 *                 elements is reversed.
 * @param [options.structure.isBigEndian = false] - Indicates endianness of the elements in the buffer when the
 *                  stride property is greater than 1.  If this property is false, the first element is the
 *                  low-order element.  If it is true, the first element is the high-order element.
 * @param [options.structure.lowestEncodedHeight] - The lowest value that can be stored in the height buffer.  Any heights that are lower
 *                 than this value after encoding with the `heightScale` and `heightOffset` are clamped to this value.  For example, if the height
 *                 buffer is a `Uint16Array`, this value should be 0 because a `Uint16Array` cannot store negative numbers.  If this parameter is
 *                 not specified, no minimum value is enforced.
 * @param [options.structure.highestEncodedHeight] - The highest value that can be stored in the height buffer.  Any heights that are higher
 *                 than this value after encoding with the `heightScale` and `heightOffset` are clamped to this value.  For example, if the height
 *                 buffer is a `Uint16Array`, this value should be `256 * 256 - 1` or 65535 because a `Uint16Array` cannot store numbers larger
 *                 than 65535.  If this parameter is not specified, no maximum value is enforced.
 * @param [options.encoding = HeightmapEncoding.NONE] - The encoding that is used on the buffer.
 * @param [options.createdByUpsampling = false] - True if this instance was created by upsampling another instance;
 *                  otherwise, false.

 * @param options - Object with the following properties:
 * @param options.url - The url to a tileset JSON file.
 * @param [options.show = true] - Determines if the tileset will be shown.
 * @param [options.modelMatrix = Matrix4.IDENTITY] - A 4x4 transformation matrix that transforms the tileset's root tile.
 * @param [options.shadows = ShadowMode.ENABLED] - Determines whether the tileset casts or receives shadows from light sources.
 * @param [options.maximumScreenSpaceError = 16] - The maximum screen space error used to drive level of detail refinement.
 * @param [options.maximumMemoryUsage = 512] - The maximum amount of memory in MB that can be used by the tileset.
 * @param [options.cullWithChildrenBounds = true] - Optimization option. Whether to cull tiles using the union of their children bounding volumes.
 * @param [options.cullRequestsWhileMoving = true] - Optimization option. Don't request tiles that will likely be unused when they come back because of the camera's movement. This optimization only applies to stationary tilesets.
 * @param [options.cullRequestsWhileMovingMultiplier = 60.0] - Optimization option. Multiplier used in culling requests while moving. Larger is more aggressive culling, smaller less aggressive culling.
 * @param [options.preloadWhenHidden = false] - Preload tiles when <code>tileset.show</code> is <code>false</code>. Loads tiles as if the tileset is visible but does not render them.
 * @param [options.preloadFlightDestinations = true] - Optimization option. Preload tiles at the camera's flight destination while the camera is in flight.
 * @param [options.preferLeaves = false] - Optimization option. Prefer loading of leaves first.
 * @param [options.dynamicScreenSpaceError = false] - Optimization option. Reduce the screen space error for tiles that are further away from the camera.
 * @param [options.dynamicScreenSpaceErrorDensity = 0.00278] - Density used to adjust the dynamic screen space error, similar to fog density.
 * @param [options.dynamicScreenSpaceErrorFactor = 4.0] - A factor used to increase the computed dynamic screen space error.
 * @param [options.dynamicScreenSpaceErrorHeightFalloff = 0.25] - A ratio of the tileset's height at which the density starts to falloff.
 * @param [options.progressiveResolutionHeightFraction = 0.3] - Optimization option. If between (0.0, 0.5], tiles at or above the screen space error for the reduced screen resolution of <code>progressiveResolutionHeightFraction*screenHeight</code> will be prioritized first. This can help get a quick layer of tiles down while full resolution tiles continue to load.
 * @param [options.foveatedScreenSpaceError = true] - Optimization option. Prioritize loading tiles in the center of the screen by temporarily raising the screen space error for tiles around the edge of the screen. Screen space error returns to normal once all the tiles in the center of the screen as determined by the {@link Cesium3DTileset#foveatedConeSize} are loaded.
 * @param [options.foveatedConeSize = 0.1] - Optimization option. Used when {@link Cesium3DTileset#foveatedScreenSpaceError} is true to control the cone size that determines which tiles are deferred. Tiles that are inside this cone are loaded immediately. Tiles outside the cone are potentially deferred based on how far outside the cone they are and their screen space error. This is controlled by {@link Cesium3DTileset#foveatedInterpolationCallback} and {@link Cesium3DTileset#foveatedMinimumScreenSpaceErrorRelaxation}. Setting this to 0.0 means the cone will be the line formed by the camera position and its view direction. Setting this to 1.0 means the cone encompasses the entire field of view of the camera, disabling the effect.
 * @param [options.foveatedMinimumScreenSpaceErrorRelaxation = 0.0] - Optimization option. Used when {@link Cesium3DTileset#foveatedScreenSpaceError} is true to control the starting screen space error relaxation for tiles outside the foveated cone. The screen space error will be raised starting with tileset value up to {@link Cesium3DTileset#maximumScreenSpaceError} based on the provided {@link Cesium3DTileset#foveatedInterpolationCallback}.
 * @param [options.foveatedInterpolationCallback = Math.lerp] - Optimization option. Used when {@link Cesium3DTileset#foveatedScreenSpaceError} is true to control how much to raise the screen space error for tiles outside the foveated cone, interpolating between {@link Cesium3DTileset#foveatedMinimumScreenSpaceErrorRelaxation} and {@link Cesium3DTileset#maximumScreenSpaceError}
 * @param [options.foveatedTimeDelay = 0.2] - Optimization option. Used when {@link Cesium3DTileset#foveatedScreenSpaceError} is true to control how long in seconds to wait after the camera stops moving before deferred tiles start loading in. This time delay prevents requesting tiles around the edges of the screen when the camera is moving. Setting this to 0.0 will immediately request all tiles in any given view.
 * @param [options.skipLevelOfDetail = false] - Optimization option. Determines if level of detail skipping should be applied during the traversal.
 * @param [options.baseScreenSpaceError = 1024] - When <code>skipLevelOfDetail</code> is <code>true</code>, the screen space error that must be reached before skipping levels of detail.
 * @param [options.skipScreenSpaceErrorFactor = 16] - When <code>skipLevelOfDetail</code> is <code>true</code>, a multiplier defining the minimum screen space error to skip. Used in conjunction with <code>skipLevels</code> to determine which tiles to load.
 * @param [options.skipLevels = 1] - When <code>skipLevelOfDetail</code> is <code>true</code>, a constant defining the minimum number of levels to skip when loading tiles. When it is 0, no levels are skipped. Used in conjunction with <code>skipScreenSpaceErrorFactor</code> to determine which tiles to load.
 * @param [options.immediatelyLoadDesiredLevelOfDetail = false] - When <code>skipLevelOfDetail</code> is <code>true</code>, only tiles that meet the maximum screen space error will ever be downloaded. Skipping factors are ignored and just the desired tiles are loaded.
 * @param [options.loadSiblings = false] - When <code>skipLevelOfDetail</code> is <code>true</code>, determines whether siblings of visible tiles are always downloaded during traversal.
 * @param [options.clippingPlanes] - The {@link ClippingPlaneCollection} used to selectively disable rendering the tileset.
 * @param [options.classificationType] - Determines whether terrain, 3D Tiles or both will be classified by this tileset. See {@link Cesium3DTileset#classificationType} for details about restrictions and limitations.
 * @param [options.ellipsoid = Ellipsoid.WGS84] - The ellipsoid determining the size and shape of the globe.
 * @param [options.pointCloudShading] - Options for constructing a {@link PointCloudShading} object to control point attenuation based on geometric error and lighting.
 * @param [options.lightColor] - The light color when shading models. When <code>undefined</code> the scene's light color is used instead.
 * @param [options.imageBasedLighting] - The properties for managing image-based lighting for this tileset.
 * @param [options.backFaceCulling = true] - Whether to cull back-facing geometry. When true, back face culling is determined by the glTF material's doubleSided property; when false, back face culling is disabled.
 * @param [options.showOutline = true] - Whether to display the outline for models using the {@link https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Vendor/CESIUM_primitive_outline|CESIUM_primitive_outline} extension. When true, outlines are displayed. When false, outlines are not displayed.
 * @param [options.vectorClassificationOnly = false] - Indicates that only the tileset's vector tiles should be used for classification.
 * @param [options.vectorKeepDecodedPositions = false] - Whether vector tiles should keep decoded positions in memory. This is used with {@link Cesium3DTileFeature.getPolylinePositions}.
 * @param [options.featureIdLabel = "featureId_0"] - Label of the feature ID set to use for picking and styling. For EXT_mesh_features, this is the feature ID's label property, or "featureId_N" (where N is the index in the featureIds array) when not specified. EXT_feature_metadata did not have a label field, so such feature ID sets are always labeled "featureId_N" where N is the index in the list of all feature Ids, where feature ID attributes are listed before feature ID textures. If featureIdLabel is an integer N, it is converted to the string "featureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
 * @param [options.instanceFeatureIdLabel = "instanceFeatureId_0"] - Label of the instance feature ID set used for picking and styling. If instanceFeatureIdLabel is set to an integer N, it is converted to the string "instanceFeatureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
 * @param [options.showCreditsOnScreen = false] - Whether to display the credits of this tileset on screen.
 * @param [options.splitDirection = SplitDirection.NONE] - The {@link SplitDirection} split to apply to this tileset.
 * @param [options.debugHeatmapTilePropertyName] - The tile variable to colorize as a heatmap. All rendered tiles will be colorized relative to each other's specified variable value.
 * @param [options.debugFreezeFrame = false] - For debugging only. Determines if only the tiles from last frame should be used for rendering.
 * @param [options.debugColorizeTiles = false] - For debugging only. When true, assigns a random color to each tile.
 * @param [options.enableDebugWireframe] - For debugging only. This must be true for debugWireframe to work for ModelExperimental in WebGL1. This cannot be set after the tileset has loaded.
 * @param [options.debugWireframe = false] - For debugging only. When true, render's each tile's content as a wireframe.
 * @param [options.debugShowBoundingVolume = false] - For debugging only. When true, renders the bounding volume for each tile.
 * @param [options.debugShowContentBoundingVolume = false] - For debugging only. When true, renders the bounding volume for each tile's content.
 * @param [options.debugShowViewerRequestVolume = false] - For debugging only. When true, renders the viewer request volume for each tile.
 * @param [options.debugShowGeometricError = false] - For debugging only. When true, draws labels to indicate the geometric error of each tile.
 * @param [options.debugShowRenderingStatistics = false] - For debugging only. When true, draws labels to indicate the number of commands, points, triangles and features for each tile.
 * @param [options.debugShowMemoryUsage = false] - For debugging only. When true, draws labels to indicate the texture and geometry memory in megabytes used by each tile.
 * @param [options.debugShowUrl = false] - For debugging only. When true, draws labels to indicate the url of each tile.

 * A classification primitive represents a volume enclosing geometry in the {@link Scene} to be highlighted.
 * <p>
 * A primitive combines geometry instances with an {@link Appearance} that describes the full shading, including
 * {@link Material} and {@link RenderState}.  Roughly, the geometry instance defines the structure and placement,
 * and the appearance defines the visual characteristics.  Decoupling geometry and appearance allows us to mix
 * and match most of them and add a new geometry or appearance independently of each other.
 * Only {@link PerInstanceColorAppearance} with the same color across all instances is supported at this time when using
 * ClassificationPrimitive directly.
 * For full {@link Appearance} support when classifying terrain or 3D Tiles use {@link GroundPrimitive} instead.
 * </p>
 * <p>
 * For correct rendering, this feature requires the EXT_frag_depth WebGL extension. For hardware that do not support this extension, there
 * will be rendering artifacts for some viewing angles.
 * </p>
 * <p>
 * Valid geometries are {@link BoxGeometry}, {@link CylinderGeometry}, {@link EllipsoidGeometry}, {@link PolylineVolumeGeometry}, and {@link SphereGeometry}.
 * </p>
 * <p>
 * Geometries that follow the surface of the ellipsoid, such as {@link CircleGeometry}, {@link CorridorGeometry}, {@link EllipseGeometry}, {@link PolygonGeometry}, and {@link RectangleGeometry},
 * are also valid if they are extruded volumes; otherwise, they will not be rendered.
 * </p>

 * @param [options.geometryInstances] - The geometry instances to render. This can either be a single instance or an array of length one.
 * @param [options.appearance] - The appearance used to render the primitive. Defaults to PerInstanceColorAppearance when GeometryInstances have a color attribute.
 * @param [options.show = true] - Determines if this primitive will be shown.
 * @param [options.vertexCacheOptimize = false] - When <code>true</code>, geometry vertices are optimized for the pre and post-vertex-shader caches.
 * @param [options.interleave = false] - When <code>true</code>, geometry vertex attributes are interleaved, which can slightly improve rendering performance but increases load time.
 * @param [options.compressVertices = true] - When <code>true</code>, the geometry vertices are compressed, which will save memory.
 * @param [options.releaseGeometryInstances = true] - When <code>true</code>, the primitive does not keep a reference to the input <code>geometryInstances</code> to save memory.
 * @param [options.allowPicking = true] - When <code>true</code>, each geometry instance will only be pickable with {@link Scene#pick}.  When <code>false</code>, GPU memory is saved.
 * @param [options.asynchronous = true] - Determines if the primitive will be created asynchronously or block until ready. If false initializeTerrainHeights() must be called first.
 * @param [options.classificationType = ClassificationType.BOTH] - Determines whether terrain, 3D Tiles or both will be classified.
 * @param [options.debugShowBoundingVolume = false] - For debugging only. Determines if this primitive's commands' bounding spheres are shown.

 * A ground primitive represents geometry draped over terrain or 3D Tiles in the {@link Scene}.
 * <p>
 * A primitive combines geometry instances with an {@link Appearance} that describes the full shading, including
 * {@link Material} and {@link RenderState}.  Roughly, the geometry instance defines the structure and placement,
 * and the appearance defines the visual characteristics.  Decoupling geometry and appearance allows us to mix
 * and match most of them and add a new geometry or appearance independently of each other.
 * </p>
 * <p>
 * Support for the WEBGL_depth_texture extension is required to use GeometryInstances with different PerInstanceColors
 * or materials besides PerInstanceColorAppearance.
 * </p>
 * <p>
 * Textured GroundPrimitives were designed for notional patterns and are not meant for precisely mapping
 * textures to terrain - for that use case, use {@link SingleTileImageryProvider}.
 * </p>
 * <p>
 * For correct rendering, this feature requires the EXT_frag_depth WebGL extension. For hardware that do not support this extension, there
 * will be rendering artifacts for some viewing angles.

 * @param [options.allowPicking = true] - When <code>true</code>, each glTF mesh and primitive is pickable with {@link Scene#pick}.
 * @param [options.incrementallyLoadTextures = true] - Determine if textures may continue to stream in after the model is loaded.
 * @param [options.asynchronous = true] - Determines if model WebGL resource creation will be spread out over several frames or block until completion once all glTF files are loaded.
 * @param [options.clampAnimations = true] - Determines if the model's animations should hold a pose over frames where no keyframes are specified.
 * @param [options.shadows = ShadowMode.ENABLED] - Determines whether the model casts or receives shadows from light sources.
 * @param [options.debugShowBoundingVolume = false] - For debugging only. Draws the bounding sphere for each draw command in the model.

     * @param [options.show = true] - Determines if the model primitive will be shown.
     * @param [options.modelMatrix = Matrix4.IDENTITY] - The 4x4 transformation matrix that transforms the model from model to world coordinates.
     * @param [options.scale = 1.0] - A uniform scale applied to this model.
     * @param [options.minimumPixelSize = 0.0] - The approximate minimum pixel size of the model regardless of zoom.
     * @param [options.maximumScale] - The maximum scale for the model.
     * @param [options.id] - A user-defined object to return when the model is picked with {@link Scene#pick}.
     * @param [options.allowPicking = true] - When <code>true</code>, each glTF mesh and primitive is pickable with {@link Scene#pick}.
     * @param [options.incrementallyLoadTextures = true] - Determine if textures may continue to stream in after the model is loaded.
     * @param [options.asynchronous = true] - Determines if model WebGL resource creation will be spread out over several frames or block until completion once all glTF files are loaded.
     * @param [options.clampAnimations = true] - Determines if the model's animations should hold a pose over frames where no keyframes are specified.
     * @param [options.shadows = ShadowMode.ENABLED] - Determines whether the model casts or receives shadows from light sources.
     * @param [options.debugShowBoundingVolume = false] - For debugging only. Draws the bounding sphere for each draw command in the model.

     * @param [options.colorBlendAmount = 0.5] - Value used to determine the color strength when the <code>colorBlendMode</code> is <code>MIX</code>. A value of 0.0 results in the model's rendered color while a value of 1.0 results in a solid color, with any value in-between resulting in a mix of the two.
     * @param [options.silhouetteColor = Color.RED] - The silhouette color. If more than 256 models have silhouettes enabled, there is a small chance that overlapping models will have minor artifacts.
     * @param [options.silhouetteSize = 0.0] - The size of the silhouette in pixels.
     * @param [options.clippingPlanes] - The {@link ClippingPlaneCollection} used to selectively disable rendering the model.

 * @param [options.maximumScale] - The maximum scale size of a model. An upper limit for minimumPixelSize.
 * @param [options.clampAnimations = true] - Determines if the model's animations should hold a pose over frames where no keyframes are specified.
 * @param [options.debugShowBoundingVolume = false] - For debugging only. Draws the bounding sphere for each draw command in the model.
 * @param [options.enableDebugWireframe = false] - For debugging only. This must be set to true for debugWireframe to work in WebGL1. This cannot be set after the model has loaded.
 * @param [options.debugWireframe = false] - For debugging only. Draws the model in wireframe. Will only work for WebGL1 if enableDebugWireframe is set to true.
 * @param [options.cull = true] - Whether or not to cull the model using frustum/horizon culling. If the model is part of a 3D Tiles tileset, this property will always be false, since the 3D Tiles culling system is used.
 * @param [options.opaquePass = Pass.OPAQUE] - The pass to use in the {@link DrawCommand} for the opaque portions of the model.
 * @param [options.allowPicking = true] - When <code>true</code>, each primitive is pickable with {@link Scene#pick}.
 * @param [options.customShader] - A custom shader. This will add user-defined GLSL code to the vertex and fragment shaders. Using custom shaders with a {@link Cesium3DTileStyle} may lead to undefined behavior.
 * @param [options.content] - The tile content this model belongs to. This property will be undefined if model is not loaded as part of a tileset.
 * @param [options.show = true] - Whether or not to render the model.
 * @param [options.color] - A color that blends with the model's rendered color.
 * @param [options.colorBlendMode = ColorBlendMode.HIGHLIGHT] - Defines how the color blends with the model.
 * @param [options.colorBlendAmount = 0.5] - Value used to determine the color strength when the <code>colorBlendMode</code> is <code>MIX</code>. A value of 0.0 results in the model's rendered color while a value of 1.0 results in a solid color, with any value in-between resulting in a mix of the two.
 * @param [options.featureIdLabel = "featureId_0"] - Label of the feature ID set to use for picking and styling. For EXT_mesh_features, this is the feature ID's label property, or "featureId_N" (where N is the index in the featureIds array) when not specified. EXT_feature_metadata did not have a label field, so such feature ID sets are always labeled "featureId_N" where N is the index in the list of all feature Ids, where feature ID attributes are listed before feature ID textures. If featureIdLabel is an integer N, it is converted to the string "featureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
 * @param [options.instanceFeatureIdLabel = "instanceFeatureId_0"] - Label of the instance feature ID set used for picking and styling. If instanceFeatureIdLabel is set to an integer N, it is converted to the string "instanceFeatureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
 * @param [options.pointCloudShading] - Options for constructing a {@link PointCloudShading} object to control point attenuation based on geometric error and lighting.
 * @param [options.clippingPlanes] - The {@link ClippingPlaneCollection} used to selectively disable rendering the model.
 * @param [options.lightColor] - The light color when shading the model. When <code>undefined</code> the scene's light color is used instead.
 * @param [options.imageBasedLighting] - The properties for managing image-based lighting on this model.
 * @param [options.backFaceCulling = true] - Whether to cull back-facing geometry. When true, back face culling is determined by the material's doubleSided property; when false, back face culling is disabled. Back faces are not culled if the model's color is translucent.
 * @param [options.shadows = ShadowMode.ENABLED] - Determines whether the model casts or receives shadows from light sources.
 * @param [options.showCreditsOnScreen = false] - Whether to display the credits of this model on screen.
 * @param [options.splitDirection = SplitDirection.NONE] - The {@link SplitDirection} split to apply to this model.
 * @param [options.projectTo2D = false] - Whether to accurately project the model's positions in 2D. If a model is part of a 3D Tiles tileset, this will always be true. If this is false, the model will show up in 2D / CV mode but its positions may be inaccurate. This disables minimumPixelSize and prevents future modification to its model matrix. This also cannot be set after the model has loaded.

     * </p>
     * <p>
     * The model can be a traditional glTF asset with a .gltf extension or a Binary glTF using the .glb extension.
     * @param options - Object with the following properties:
     * @param options.url - The url to the .gltf or .glb file.
     * @param [options.basePath = ''] - The base path that paths in the glTF JSON are relative to.
     * @param [options.modelMatrix = Matrix4.IDENTITY] - The 4x4 transformation matrix that transforms the model from model to world coordinates.
     * @param [options.scale = 1.0] - A uniform scale applied to this model.
     * @param [options.minimumPixelSize = 0.0] - The approximate minimum pixel size of the model regardless of zoom.
     * @param [options.maximumScale] - The maximum scale size of a model. An upper limit for minimumPixelSize.
     * @param [options.incrementallyLoadTextures = true] - Determine if textures may continue to stream in after the model is loaded.
     * @param [options.releaseGltfJson = false] - When true, the glTF JSON is released once the glTF is loaded. This is is especially useful for cases like 3D Tiles, where each .gltf model is unique and caching the glTF JSON is not effective.
     * @param [options.debugShowBoundingVolume = false] - For debugging only. Draws the bounding sphere for each draw command in the model.
     * @param [options.enableDebugWireframe = false] - For debugging only. This must be set to true for debugWireframe to work in WebGL1. This cannot be set after the model has loaded.
     * @param [options.debugWireframe = false] - For debugging only. Draws the model in wireframe. Will only work for WebGL1 if enableDebugWireframe is set to true.
     * @param [options.cull = true] - Whether or not to cull the model using frustum/horizon culling. If the model is part of a 3D Tiles tileset, this property will always be false, since the 3D Tiles culling system is used.
     * @param [options.opaquePass = Pass.OPAQUE] - The pass to use in the {@link DrawCommand} for the opaque portions of the model.
     * @param [options.upAxis = Axis.Y] - The up-axis of the glTF model.
     * @param [options.forwardAxis = Axis.Z] - The forward-axis of the glTF model.
     * @param [options.allowPicking = true] - When <code>true</code>, each primitive is pickable with {@link Scene#pick}.
     * @param [options.customShader] - A custom shader. This will add user-defined GLSL code to the vertex and fragment shaders. Using custom shaders with a {@link Cesium3DTileStyle} may lead to undefined behavior.
     * @param [options.content] - The tile content this model belongs to. This property will be undefined if model is not loaded as part of a tileset.
     * @param [options.show = true] - Whether or not to render the model.
     * @param [options.color] - A color that blends with the model's rendered color.
     * @param [options.colorBlendMode = ColorBlendMode.HIGHLIGHT] - Defines how the color blends with the model.
     * @param [options.colorBlendAmount = 0.5] - Value used to determine the color strength when the <code>colorBlendMode</code> is <code>MIX</code>. A value of 0.0 results in the model's rendered color while a value of 1.0 results in a solid color, with any value in-between resulting in a mix of the two.
     * @param [options.featureIdLabel = "featureId_0"] - Label of the feature ID set to use for picking and styling. For EXT_mesh_features, this is the feature ID's label property, or "featureId_N" (where N is the index in the featureIds array) when not specified. EXT_feature_metadata did not have a label field, so such feature ID sets are always labeled "featureId_N" where N is the index in the list of all feature Ids, where feature ID attributes are listed before feature ID textures. If featureIdLabel is an integer N, it is converted to the string "featureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
     * @param [options.instanceFeatureIdLabel = "instanceFeatureId_0"] - Label of the instance feature ID set used for picking and styling. If instanceFeatureIdLabel is set to an integer N, it is converted to the string "instanceFeatureId_N" automatically. If both per-primitive and per-instance feature IDs are present, the instance feature IDs take priority.
     * @param [options.pointCloudShading] - Options for constructing a {@link PointCloudShading} object to control point attenuation and lighting.
     * @param [options.clippingPlanes] - The {@link ClippingPlaneCollection} used to selectively disable rendering the model.
     * @param [options.lightColor] - The light color when shading the model. When <code>undefined</code> the scene's light color is used instead.
     * @param [options.imageBasedLighting] - The properties for managing image-based lighting on this model.
     * @param [options.backFaceCulling = true] - Whether to cull back-facing geometry. When true, back face culling is determined by the material's doubleSided property; when false, back face culling is disabled. Back faces are not culled if the model's color is translucent.
     * @param [options.shadows = ShadowMode.ENABLED] - Determines whether the model casts or receives shadows from light sources.
     * @param [options.showCreditsOnScreen = false] - Whether to display the credits of this model on screen.
     * @param [options.splitDirection = SplitDirection.NONE] - The {@link SplitDirection} split to apply to this model.
     * @param [options.projectTo2D = false] - Whether to accurately project the model's positions in 2D. If a model is part of a 3D Tiles tileset, this will always be true. If this is false, the model will show up in 2D / CV mode but its positions may be inaccurate. This disables minimumPixelSize and prevents future modification to its model matrix. This also cannot be set after the model has loaded.
     * @returns The newly created model.

 * A primitive represents geometry in the {@link Scene}.  The geometry can be from a single {@link GeometryInstance}
 * as shown in example 1 below, or from an array of instances, even if the geometry is from different
 * geometry types, e.g., an {@link RectangleGeometry} and an {@link EllipsoidGeometry} as shown in Code Example 2.
 * <p>
 * A primitive combines geometry instances with an {@link Appearance} that describes the full shading, including
 * {@link Material} and {@link RenderState}.  Roughly, the geometry instance defines the structure and placement,
 * and the appearance defines the visual characteristics.  Decoupling geometry and appearance allows us to mix
 * and match most of them and add a new geometry or appearance independently of each other.
 * </p>
 * <p>
 * Combining multiple instances into one primitive is called batching, and significantly improves performance for static data.
 * Instances can be individually picked; {@link Scene#pick} returns their {@link GeometryInstance#id}.  Using
 * per-instance appearances like {@link PerInstanceColorAppearance}, each instance can also have a unique color.
 * </p>
 * <p>
 * {@link Geometry} can either be created and batched on a web worker or the main thread. The first two examples
 * show geometry that will be created on a web worker by using the descriptions of the geometry. The third example
 * shows how to create the geometry on the main thread by explicitly calling the <code>createGeometry</code> method.

 * <img src="Images/AnimationWidget.png" width="211" height="142" alt="" />
 * <br />Animation widget
 * </span>
 * <br /><br />
 * The Animation widget provides buttons for play, pause, and reverse, along with the
 * current time and date, surrounded by a "shuttle ring" for controlling the speed of animation.
 * <br /><br />
 * The "shuttle ring" concept is borrowed from video editing, where typically a
 * "jog wheel" can be rotated to move past individual animation frames very slowly, and
 * a surrounding shuttle ring can be twisted to control direction and speed of fast playback.
 * Cesium typically treats time as continuous (not broken into pre-defined animation frames),
 * so this widget offers no jog wheel.  Instead, the shuttle ring is capable of both fast and
 * very slow playback.  Click and drag the shuttle ring pointer itself (shown above in green),
 * or click in the rest of the ring area to nudge the pointer to the next preset speed in that direction.
 * <br /><br />
 * The Animation widget also provides a "realtime" button (in the upper-left) that keeps
 * animation time in sync with the end user's system clock, typically displaying
 * "today" or "right now."  This mode is not available in {@link ClockRange.CLAMPED} or
 * {@link ClockRange.LOOP_STOP} mode if the current time is outside of {@link Clock}'s startTime and endTime.
 * @example
 * // In HTML head, include a link to Animation.css stylesheet,
 * // and in the body, include: <div id="animationContainer"></div>
 *
 * const clock = new Cesium.Clock();
 * const clockViewModel = new Cesium.ClockViewModel(clock);
 * const viewModel = new Cesium.AnimationViewModel(clockViewModel);
 * const widget = new Cesium.Animation('animationContainer', viewModel);
 *

 * @param container - The DOM element or ID that will contain the widget.
 * @param [options] - Object with the following properties:
 * @param [options.clock = new Clock()] - The clock to use to control current time.
 * @param [options.imageryProvider = createWorldImagery()] - The imagery provider to serve as the base layer. If set to <code>false</code>, no imagery provider will be added.
 * @param [options.terrainProvider = new EllipsoidTerrainProvider] - The terrain provider.
 * @param [options.skyBox] - The skybox used to render the stars.  When <code>undefined</code>, the default stars are used. If set to <code>false</code>, no skyBox, Sun, or Moon will be added.
 * @param [options.skyAtmosphere] - Blue sky, and the glow around the Earth's limb.  Set to <code>false</code> to turn it off.
 * @param [options.sceneMode = SceneMode.SCENE3D] - The initial scene mode.
 * @param [options.scene3DOnly = false] - When <code>true</code>, each geometry instance will only be rendered in 3D to save GPU memory.
 * @param [options.orderIndependentTranslucency = true] - If true and the configuration supports it, use order independent translucency.
 * @param [options.mapProjection = new GeographicProjection()] - The map projection to use in 2D and Columbus View modes.
 * @param [options.globe = new Globe(mapProjection.ellipsoid)] - The globe to use in the scene.  If set to <code>false</code>, no globe will be added.
 * @param [options.useDefaultRenderLoop = true] - True if this widget should control the render loop, false otherwise.
 * @param [options.useBrowserRecommendedResolution = true] - If true, render at the browser's recommended resolution and ignore <code>window.devicePixelRatio</code>.
 * @param [options.targetFrameRate] - The target frame rate when using the default render loop.
 * @param [options.showRenderLoopErrors = true] - If true, this widget will automatically display an HTML panel to the user containing the error, if a render loop error occurs.
 * @param [options.contextOptions] - Context and WebGL creation properties corresponding to <code>options</code> passed to {@link Scene}.
 * @param [options.creditContainer] - The DOM element or ID that will contain the {@link CreditDisplay}.  If not specified, the credits are added
 *        to the bottom of the widget itself.
 * @param [options.creditViewport] - The DOM element or ID that will contain the credit pop up created by the {@link CreditDisplay}.  If not specified, it will appear over the widget itself.
 * @param [options.shadows = false] - Determines if shadows are cast by light sources.
 * @param [options.terrainShadows = ShadowMode.RECEIVE_ONLY] - Determines if the terrain casts or receives shadows from light sources.
 * @param [options.mapMode2D = MapMode2D.INFINITE_SCROLL] - Determines if the 2D map is rotatable or can be scrolled infinitely in the horizontal direction.
 * @param [options.requestRenderMode = false] - If true, rendering a frame will only occur when needed as determined by changes within the scene. Enabling improves performance of the application, but requires using {@link Scene#requestRender} to render a new frame explicitly in this mode. This will be necessary in many cases after making changes to the scene in other parts of the API. See {@link https://cesium.com/blog/2018/01/24/cesium-scene-rendering-performance/|Improving Performance with Explicit Rendering}.
 * @param [options.maximumRenderTimeChange = 0.0] - If requestRenderMode is true, this value defines the maximum change in simulation time allowed before a render is requested. See {@link https://cesium.com/blog/2018/01/24/cesium-scene-rendering-performance/|Improving Performance with Explicit Rendering}.
 * @param [options.msaaSamples = 1] - If provided, this value controls the rate of multisample antialiasing. Typical multisampling rates are 2, 4, and sometimes 8 samples per pixel. Higher sampling rates of MSAA may impact performance in exchange for improved visual quality. This value only applies to WebGL2 contexts that support multisample render targets.

     * @property [msaaSamples = 1] - If provided, this value controls the rate of multisample antialiasing. Typical multisampling rates are 2, 4, and sometimes 8 samples per pixel. Higher sampling rates of MSAA may impact performance in exchange for improved visual quality. This value only applies to WebGL2 contexts that support multisample render targets.
