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.

Object |
optional
Object with the following properties:
|
Members
articulations : PropertyBag
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.
clampAnimations : Property
Gets or sets the boolean Property specifying if glTF animations should hold the last pose for time durations with no keyframes.
-
Default Value:
true
clippingPlanes : Property
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.
-
Default Value:
Color.WHITE
colorBlendAmount : Property
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
colorBlendMode : Property
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.
heightReference : Property
Gets or sets the Property specifying the
HeightReference.
-
Default Value:
HeightReference.NONE
imageBasedLightingFactor : Property
A property specifying the
Cartesian2 used to scale the diffuse and specular image-based lighting contribution to the final color.
incrementallyLoadTextures : Property
Get or sets the boolean Property specifying whether textures
may continue to stream in after the model is loaded.
lightColor : Property
A property specifying the
Cartesian3 color of the light source when shading the model.
maximumScale : Property
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.
minimumPixelSize : Property
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
nodeTransformations : PropertyBag
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.
runAnimations : Property
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
shadows : Property
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
silhouetteColor : Property
Gets or sets the Property specifying the
Color of the silhouette.
-
Default Value:
Color.RED
silhouetteSize : Property
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.
