Module particle_render 

GPU particle rendering bridge — renders particles directly from compute SSBO using indirect draw, with zero CPU readback.

The render pipeline reads from the SSBO that was written by particle_update.comp and draws instanced quads (one per alive particle) using the standard glyph vertex format. The indirect draw buffer’s instance count is written by the compute shader, so the CPU never needs to know how many particles are alive.

Structs

DepthLayerConfig

Configuration for rendering particles across multiple depth layers.

ParticleRenderConfig

Configuration for GPU particle rendering.

ParticleRenderInstance

Per-particle data extracted from the SSBO for rendering.

Enums

ParticleLodTier

LOD tier for particle rendering based on camera distance.

Constants

PARTICLE_FRAG_SRC

Fragment shader for GPU particles.

PARTICLE_VERT_SRC

Vertex shader that reads particle data from SSBO and renders instanced quads.

Functions

extract_render_instances

Extract render instances from a CPU-side particle buffer.

sort_instances_back_to_front

Sort render instances back-to-front relative to the camera position.
