ray marched <Caustics> new in drei 💫
beautiful swirls and patterns that appear when light passes through transmissive surfaces. 😍 this was a huge effort by ! react + threejs users just have to type:
<Caustics {...config}>
<Model />

btw yes it's great for static scenes but actually fast enough for 120fps runtime +moving objs 🫠

Alright - got a caustics computation working by raytracing quads. 0-bounce caustics just use simple render targets (no rt) and run very smoothly. Support different ior and light area. These aren't faked - based directly on mesh curvature!
