threejs-temporal-surfaces

Build view-aligned and screen-space surface effects in Three.js. Use for touch-history frost and thaw, ping-pong accumulation, reduced-resolution blur, crystalline masks, two-scale refraction, and procedural rain droplets that refract and blur a background through wet glass.

# Temporal Surfaces

Choose persistent history or procedural screen-space evolution explicitly. Do
not fake accumulation with time-only noise, and do not allocate history for an
effect whose complete state is analytic in time.

This skill contains exemplary examples and assets beyond descriptive guidance,
they're worth studying, referencing, or even copying. Use them sufficiently
when relevant and do NOT blindly skip them.
