constructor(sector: Sector)

Properties

sector

val sector: Sector

The sector spanned by this tile.

Functions

distanceToCamera

fun distanceToCamera(rc: RenderContext): Double

Distance from this tile's nearest point to the camera, cached per camera position and elevation timestamp so the fog cull and the subdivision test share one computation per frame. 3D globes only - offset (2D continuous) globes reposition tiles without moving the camera point.

intersectsFrustum

fun intersectsFrustum(rc: RenderContext): Boolean

Indicates whether this tile's Cartesian extent intersects a frustum.

intersectsSector

fun intersectsSector(sector: Sector): Boolean

Indicates whether this tile intersects a specified sector.
