THREE.JS / FOUNDATIONS — SHADOW PERFORMANCE

A field of moving casters.

Measure a deterministic animated-caster field under one shadow-casting SunLight-family reference: PCF shadow-map configuration, receiver ownership, instance count, and CPU-side render samples stay explicit.

Shadow performance contract

One directional shadow view owns the map budget while an InstancedMesh owns the caster population. Samples report render time plus Renderer.info submission counters; they are local observations, not universal GPU benchmarks.

Derived from the official WebGL shadowmap performance example, pinned source, DirectionalLight, and WebGLRenderer contracts. This bounded study does not claim whole-example fidelity.
