ConstructorOptions

Properties

The billboard blending option. The default is used for rendering both opaque and translucent billboards. However, if either all of the billboards are completely opaque or all are completely translucent, setting the technique to BlendOption.OPAQUE or BlendOption.TRANSLUCENT can improve performance by up to 2x. Default value - BlendOption.OPAQUE_AND_TRANSLUCENT

coarseDepthTestDistance

abstract val coarseDepthTestDistance: Double?

The distance from the camera, beyond which, billboards are depth-tested against an approximation of the globe ellipsoid rather than against the full globe depth buffer. If unspecified, the default value is determined relative to the value of Ellipsoid.default.

debugShowBoundingVolume

abstract val debugShowBoundingVolume: Boolean?

For debugging only. Determines if this primitive's commands' bounding spheres are shown. Default value - false

modelMatrix

abstract val modelMatrix: Matrix4?

The 4x4 transformation matrix that transforms each billboard from model to world coordinates. Default value - Matrix4.IDENTITY

scene

abstract val scene: Scene?

Must be passed in for billboards that use the height reference property or will be depth tested against the globe.

show

abstract val show: Boolean?

Determines if the billboards in the collection will be shown. Default value - true

threePointDepthTestDistance

abstract val threePointDepthTestDistance: Double?

The distance from the camera, within which, billboards with a Billboard.heightReference value of HeightReference.CLAMP_TO_GROUND or HeightReference.CLAMP_TO_TERRAIN are depth tested against three key points. This ensures that if any key point of the billboard is visible, the whole billboard will be visible. If unspecified, the default value is determined relative to the value of Ellipsoid.default.
