Class: GPUParticleSystem
Defined in: src/gfx/renderJob/particle/GPUParticleSystem.ts:26
GPU-driven particle system (skeleton).
Per-particle state lives entirely in a storage buffer; a compute pass advances simulation each frame; render goes via drawIndexedIndirect so the visible-particle count is also GPU-decided. No CPU readback in the hot path → unlocks 100k+ particles at 60fps on desktop WebGPU.
Status — skeleton: this class provides the buffer + compute pipeline scaffolding and a placeholder simulate shader that advances position += velocity * dt. The render path (instanced billboards via indirect draw) is the next step; the existing packages/particle CPU particle system continues to work alongside.
Buffer layout (32 bytes / particle):
- position (vec3) + life (f32)
- velocity (vec3) + maxLife (f32)
