perf: Speed up GSplat octree evaluateNodeLods#8683
Merged
Conversation
- Pack per-node AABB min/max in GSplatOctree.nodeBoundsMinMax (Float32Array) - Inline closest-point clamp, scalar distance and forward dot - Replace Math.log LOD mapping with geometric thresholds (coarse-first scan) - Optional accumulateSplats to skip splat count when return value unused - Remove temporary evaluateNodeLods timing instrumentation

Speeds up hot-path LOD evaluation for unified GSplat octree instances (CPU-side distance + LOD band selection).
