Module geometry 

The passes that draw their own geometry into the main target: projected decals, world-space lines, and the GPU particle system.

Structs

DecalParams

Per-decal uniforms uploaded before each draw. Matches DecalParams in shaders/decal.slang. 160 bytes (two float4x4s, a float4 tint, four scalars).

DecalView

Per-frame view inputs to the projected-decal pass. Matches DecalView in shaders/decal.slang. 144 bytes.

GpuParticle

One particle slot in the pool the simulation kernel writes and the render pair reads. Matches Particle in shaders/particle_types.slang, which spells the same 32 bytes as two float4 lanes.

LineView

Per-frame view inputs to the line pass. Matches LineView in shaders/line.slang. 80 bytes.

ParticleView

Per-frame view inputs to the particle render pass. Matches ParticleView in shaders/particle.slang. 96 bytes.

SkinParams

Per-dispatch parameters for the rt_skin compute kernel, which deforms one skinned object’s bind-pose vertices into the shared deformed buffer the RT acceleration structure traces. Matches SkinParams in rt_skin.slang.
