ColladaScene

Cleanup hook invoked by close, e.g. to close a KMZ archive whose entries back this scene's textures (see loadColladaKmz). Scenes that own such a resource must be closed when discarded.

Cast/receive selector for cascaded sun shadows. Default ShadowMode.ENABLED = scene both casts onto terrain/other receivers and receives shadows on its own surface. Common opt-out: ShadowMode.RECEIVE_ONLY to drop the cascade depth pass for HUD-style or self-lit models that look wrong projected onto the ground.

Caps each texture's decoded width/height (downsampled at decode time). Default 2048 keeps photogrammetry atlases (e.g. 8192² = 256 MB decoded) within a mobile heap. Set 0 to disable.

COLLADA <up_axis>. WorldWind's local frame is ENU (Z = up), so the model's declared up is rotated onto local +Z in buildTransformationMatrix — without this a ColladaUpAxis.Y_UP photogrammetry tile renders standing vertical instead of flat on the ground.

Releases external resources held by this scene (idempotent). Textures stop loading afterwards.

Marks the cached world transform and ray-intersection geometry stale so they are rebuilt on the next render/pick. Assigning position, altitudeMode, the rotation/translation/scale properties already calls this; invoke it manually only after mutating one of them in place — e.g. correcting a KMZ model's altitude via scene.position.altitude += offset; scene.invalidate(). Terrain inputs (vertical exaggeration, and for terrain-relative modes the elevation timestamp / globe state) trigger it automatically via checkTerrainState so the model follows the resolved terrain.

Determines if the given ray intersects the shape.
