OptionalmaxMaximum primitive count per SceneGeometry — triangles for
triangle-indexed geometries (Triangles / Solid / Surface),
lines for Lines, etc. Geometries above this are split.
Default 32768 — comfortable for a single GPU batch while still
giving the renderer scope to coalesce many objects together.
OptionalmaxMaximum vertex count per SceneGeometry. Geometries above this threshold are split (see splitSceneGeometry) into two, and the resulting pieces are re-evaluated; the recursion terminates once every piece is at or below both thresholds.
Default 65535 — one less than the Uint16 quantisation cap, so
each piece's positionsCompressed slots cleanly into a u16
index space.
SceneModel to optimise. Must be populated (geometries, meshes, objects created).
Parameters for optimizeSceneModel.
