instancedmesh

Empirical benchmark of four Three.js rendering strategies populating 1,200 level props: naive individual meshes, InstancedMesh, BatchedMesh, and mergeGeometries.

Measuring the CPU updateMatrixWorld overhead across 5,000 active entities in Three.js and bypassing it via matrixAutoUpdate=false with flat Float32Array InstancedMesh matrices.

High-performance physics-to-render synchronization: binding 10,000 Rapier.js WASM rigid bodies directly into a single Three.js InstancedMesh buffer without Object3D proxies.
