open class BasicDrawableTerrain : DrawableTerrain

Types

Properties

open override var boundingSphereRadius: Double

World-space bounding sphere radius around vertexOrigin that conservatively contains every vertex of this terrain tile (including peak elevation). Used by per-cascade cullers (see earth.worldwind.layer.shadow.ShadowState.CascadeState.intersectsSphere) to skip tiles that fall entirely outside a cascade's footprint. 0 opts out of culling.

elements

var elements: BufferObject?

lineElementRange

val lineElementRange: Range

offset

open override var offset: Globe.Offset

overlayUvMatrix

open override var overlayUvMatrix: Matrix4?

World→UV matrix for draping this tile's surface-shape texture onto 3D-Tile meshes; null when unavailable this frame (no draped meshes, 2D projection, offset copies).

sector

open override val sector: Sector

triStripElementRange

val triStripElementRange: Range

vertexHeights

var vertexHeights: BufferObject?

vertexNormals

var vertexNormals: BufferObject?

vertexOrigin

open override val vertexOrigin: Vec3

vertexPoints

var vertexPoints: BufferObject?
