Traverser

class Traverser(var maxScreenSpaceError: Double = 16.0, var maxDrawDistance: Double = 0.0, var skipLevelOfDetail: Boolean = true)

Per-frame tile-tree walk. Emits selected tiles (drawables) + requested tiles (fetches).

Properties

includeShadowCasters

var includeShadowCasters: Boolean

Keep tiles outside the view frustum selected when their bounding sphere intersects a shadow cascade's light-space box - their shadows still reach visible ground. Set per traversal by the layer (shadow layer active and the layer casts shadows).

maxDrawDistance

var maxDrawDistance: Double

Skip tiles farther than this from the camera. 0 disables.

maxScreenSpaceError

var maxScreenSpaceError: Double

Target pixel error. Lower = sharper, more fetches.

skipLevelOfDetail

var skipLevelOfDetail: Boolean

OR-mode: refine on first loaded child and also select the parent as a stencil-masked fallback when any sibling is still loading. AND-mode (false) waits for every visible sibling. OR-mode is the Cesium skip-LoD default.

Functions

traverse

fun traverse(rc: RenderContext, tileset: Tileset): Traverser.Result

Reused-list result; consume before the next call.
