ModelGraphics

new Cesium.ModelGraphics(options)

A 3D model based on glTF, the runtime asset format for WebGL, OpenGL ES, and OpenGL. The position and orientation of the model is determined by the containing Entity.

Cesium includes support for glTF geometry, materials, animations, and skinning. Cameras and lights are not currently supported.

成员(属性)

Gets or sets the set of articulation values to apply to this model. This is represented as an PropertyBag, where keys are composed as the name of the articulation, a single space, and the name of the stage.
Gets or sets the boolean Property specifying if glTF animations should hold the last pose for time durations with no keyframes.
默认值: true
A property specifying the ClippingPlaneCollection used to selectively disable rendering the model.
Gets or sets the Property specifying the Color that blends with the model's rendered color.
默认值: Color.WHITE
A numeric Property specifying the color strength when the colorBlendMode is MIX. 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.
默认值: 0.5
Gets or sets the enum Property specifying how the color blends with the model.
默认值: ColorBlendMode.HIGHLIGHT
Gets or sets the CustomShader to apply to this model. When undefined, no custom shader code is used.
Gets the event that is raised whenever a property or sub-property is changed or modified.

distanceDisplayCondition : Property|undefined

Gets or sets the DistanceDisplayCondition Property specifying at what distance from the camera that this model will be displayed.
Gets or sets the Property specifying the HeightReference.
默认值: HeightReference.NONE

imageBasedLightingFactor : Property|undefined

A property specifying the Cartesian2 used to scale the diffuse and specular image-based lighting contribution to the final color.

incrementallyLoadTextures : Property|undefined

Get or sets the boolean Property specifying whether textures may continue to stream in after the model is loaded.
A property specifying the Cartesian3 light color when shading the model. When undefined the scene's light color is used instead.
Gets or sets the numeric Property specifying the maximum scale size of a model. This property is used as an upper limit for ModelGraphics#minimumPixelSize.
Gets or sets the numeric Property specifying the approximate minimum pixel size of the model regardless of zoom. This can be used to ensure that a model is visible even when the viewer zooms out. When 0.0, no minimum size is enforced.
默认值: 0.0
Gets or sets the set of node transformations to apply to this model. This is represented as an PropertyBag, where keys are names of nodes, and values are TranslationRotationScale Properties describing the transformation to apply to that node. The transformation is applied after the node's existing transformation as specified in the glTF, and does not replace the node's existing transformation.
Gets or sets the boolean Property specifying if glTF animations should be run.
默认值: true
Gets or sets the numeric Property specifying a uniform linear scale for this model. Values greater than 1.0 increase the size of the model while values less than 1.0 decrease it.
默认值: 1.0
Get or sets the enum Property specifying whether the model casts or receives shadows from light sources.
默认值: ShadowMode.ENABLED
Gets or sets the boolean Property specifying the visibility of the model.
默认值: true
Gets or sets the Property specifying the Color of the silhouette.
默认值: Color.RED
Gets or sets the numeric Property specifying the size of the silhouette in pixels.
默认值: 0.0
Gets or sets the string Property specifying the URI of the glTF asset.
