All notable changes to this project will be documented in this file.
The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

schedulingCallback
to afford flexibility in job scheduling callback for scenarios whererequestAnimationFrame
will not work, such as with WebXR.
autoDisableRendererCulling
incorrectly applying the inverse of the documented effect.- Screen space error calculations now use the camera projectionMatrix rather than camera type to determine frustum type.

path-browserify
dependency explicitly rather than relying on implicit polyfills forpath
package.
PriorityQueue.priorityCallback

PriorityQueue
to wait a frame to schedule new tasks instead of usingPromise.resolve
so tasks will only be started once per frame.
batchTable
andfeatureTable
fields onto loaded B3DM, I3DM, and PNTS scene objects directly.stopAtEmptyTiles
which defaults to true so tilesets correctly stop traversal at empty tiles.
- Tileset traversal now correctly stops at empty tiles if they do no meet the SSE requirement. Previous behavior can be retained for now by settings

tofalse
.

CMPT
,I3DM

callback function.- Support for "ADD" tile refinement.
CMPTLoader
not importingI3DMLoader
.- A case where if the tile at depth
maxDepth
was empty nothing would be rendered. - A case where an error was thrown if a mid tile had no content.
TilesRenderer.dispose
function to completely dispose of all loaded geometry, materials, and textures in the scene when the renderer is no longer needed.TilesRenderer.onDisposeModel
function which is called when a tile model is disposed of from the cache.

TilesRenderer.stats
.

update
function performance by deferring LRUCache array update.
