成员(属性)

readonly boundingSphere : BoundingSphere
engine/Source/Scene/VoxelPrimitive.js 531

Gets the bounding sphere.

clippingPlanes : ClippingPlaneCollection
engine/Source/Scene/VoxelPrimitive.js 880

The ClippingPlaneCollection used to selectively disable rendering the primitive.

customShader : CustomShader
engine/Source/Scene/VoxelPrimitive.js 896

Gets or sets the custom shader. If undefined, VoxelPrimitive.DefaultCustomShader is set.

readonly customShaderCompilationEvent : Event
engine/Source/Scene/VoxelPrimitive.js 933

Gets an event that is raised whenever a custom shader is compiled.

debugDraw : boolean
engine/Source/Scene/VoxelPrimitive.js 666

Gets or sets whether or not to render debug visualizations.

depthTest : boolean
engine/Source/Scene/VoxelPrimitive.js 685

Gets or sets whether or not to test against depth when rendering.

readonly dimensions : Cartesian3
engine/Source/Scene/VoxelPrimitive.js 590

Gets the voxel dimensions.

disableUpdate : boolean
engine/Source/Scene/VoxelPrimitive.js 647

Gets or sets whether or not the primitive should update when the view changes.

maxBounds : Cartesian3
engine/Source/Scene/VoxelPrimitive.js 815

Gets or sets the maximum bounds in the shape's local coordinate system. Voxel data is stretched or squashed to fit the bounds.

maxClippingBounds : Cartesian3
engine/Source/Scene/VoxelPrimitive.js 858

Gets or sets the maximum clipping location in the shape's local coordinate system. Any voxel content outside the range is clipped.

readonly maximumValues : Array.<Array.<number>>
engine/Source/Scene/VoxelPrimitive.js 616

Gets the maximum value per channel of the voxel data.

minBounds : Cartesian3
engine/Source/Scene/VoxelPrimitive.js 795

Gets or sets the minimum bounds in the shape's local coordinate system. Voxel data is stretched or squashed to fit the bounds.

minClippingBounds : Cartesian3
engine/Source/Scene/VoxelPrimitive.js 835

Gets or sets the minimum clipping location in the shape's local coordinate system. Any voxel content outside the range is clipped.

readonly minimumValues : Array.<Array.<number>>
engine/Source/Scene/VoxelPrimitive.js 603

Gets the minimum value per channel of the voxel data.

readonly modelMatrix : Matrix4
engine/Source/Scene/VoxelPrimitive.js 557

Gets the model matrix.

nearestSampling : boolean
engine/Source/Scene/VoxelPrimitive.js 707

Gets or sets the nearest sampling.

readonly orientedBoundingBox : OrientedBoundingBox
engine/Source/Scene/VoxelPrimitive.js 544

Gets the oriented bounding box.

readonly provider : VoxelProvider
engine/Source/Scene/VoxelPrimitive.js 518

Gets the VoxelProvider associated with this primitive.

readonly ready : boolean
engine/Source/Scene/VoxelPrimitive.js 505

Gets a value indicating whether or not the primitive is ready for use.

screenSpaceError : number
engine/Source/Scene/VoxelPrimitive.js 754

Gets or sets the screen space error in pixels. If the screen space size of a voxel is greater than the screen space error, the tile is subdivided. Lower screen space error corresponds with higher detail rendering, but could result in worse performance and higher memory consumption.

readonly shape : VoxelShapeType
engine/Source/Scene/VoxelPrimitive.js 577

Gets the shape type.

show : boolean
engine/Source/Scene/VoxelPrimitive.js 628

Gets or sets whether or not this primitive should be displayed.

stepSize : number
engine/Source/Scene/VoxelPrimitive.js 775

Gets or sets the step size multiplier used during raymarching. The lower the value, the higher the rendering quality, but also the worse the performance.

方法

destroy()
engine/Source/Scene/VoxelPrimitive.js 1663

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.
使用示例:
voxelPrimitive = voxelPrimitive && voxelPrimitive.destroy();
参考:

isDestroyed() → boolean
engine/Source/Scene/VoxelPrimitive.js 1644

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.
返回值:
true if this object was destroyed; otherwise, false.
