}

Per-particle data stored in GPU SSBO. Must be 64 bytes, aligned for std430.

Layout matches particle_update.comp exactly.

Fields

position: [f32; 3]

World-space position.

_pad0: f32

Padding for vec3 alignment.

velocity: [f32; 3]

World-space velocity.

_pad1: f32

Padding for vec3 alignment.

color: [f32; 4]

RGBA color (alpha fades over lifetime).

life: f32

Remaining life in seconds (0 = dead).

max_life: f32

Total lifespan in seconds (for computing age fraction).

size: f32

Visual size multiplier.

engine_type: u32

Which mathematical engine drives this particle’s behavior. 0=Linear, 1=Lorenz, 2=Mandelbrot, 3=Julia, 4=Rossler, 5=Aizawa, 6=Thomas, 7=Halvorsen, 8=Chen, 9=Dadras

seed: f32

Per-particle random seed for variation.

flags: u32

Particle flags (bitfield): 1=affected_by_fields, 2=has_trail, 4=collides

_reserved: [f32; 2]

Reserved for future use.
