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.

Name Type Description
options Object optional Object with the following properties:
Name Type Default Description
uri Property optional A string Property specifying the URI of the glTF asset.
show Property true optional A boolean Property specifying the visibility of the model.
scale Property 1.0 optional A numeric Property specifying a uniform linear scale.
minimumPixelSize Property 0.0 optional A numeric Property specifying the approximate minimum pixel size of the model regardless of zoom.
maximumScale Property optional The maximum scale size of a model. An upper limit for minimumPixelSize.
incrementallyLoadTextures Property true optional Determine if textures may continue to stream in after the model is loaded.
runAnimations Property true optional A boolean Property specifying if glTF animations specified in the model should be started.
nodeTransformations Property optional An object, where keys are names of nodes, and values are TranslationRotationScale Properties describing the transformation to apply to that node.
shadows Property ShadowMode.ENABLED optional An enum Property specifying whether the model casts or receives shadows from each light source.
heightReference Property HeightReference.NONE optional A Property specifying what the height is relative to.
distanceDisplayCondition Property optional A Property specifying at what distance from the camera that this model will be displayed.
silhouetteColor Property Color.RED optional A Property specifying the Color of the silhouette.
silhouetteSize Property 0.0 optional A numeric Property specifying the size of the silhouette in pixels.
color Property Color.WHITE optional A Property specifying the Color that blends with the model's rendered color.
colorBlendMode Property ColorBlendMode.HIGHLIGHT optional An enum Property specifying how the color blends with the model.
colorBlendAmount Property 0.5 optional 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.

Gets or sets the Property specifying the Color that blends with the model's rendered color.
Default Value: 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.
Default Value: 0.5
Gets or sets the enum Property specifying how the color blends with the model.
Default Value: ColorBlendMode.HIGHLIGHT

readonlydefinitionChanged : Event

Gets the event that is raised whenever a property or sub-property is changed or modified.

distanceDisplayCondition : Property

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.
Default Value: HeightReference.NONE

incrementallyLoadTextures : Property

Get or sets the boolean Property specifying whether textures may continue to stream in after the model is loaded.
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.
Default Value: 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.
Gets or sets the boolean Property specifying if glTF animations should be run.
Default Value: 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.
Default Value: 1.0
Get or sets the enum Property specifying whether the model casts or receives shadows from each light source.
Default Value: ShadowMode.ENABLED
Gets or sets the boolean Property specifying the visibility of the model.
Default Value: true
Gets or sets the Property specifying the Color of the silhouette.
Default Value: Color.RED
Gets or sets the numeric Property specifying the size of the silhouette in pixels.
Default Value: 0.0
Gets or sets the string Property specifying the URI of the glTF asset.
