Struct GpuParticleSystemItem 

#[non_exhaustive]
pub struct GpuParticleSystemItem {
    pub system_id: GpuParticleSystemId,
    pub emitter: EmitterConfig,
    pub forces: Vec<ForceField>,
    pub time_step: f32,
    pub settings: ItemSettings,
}

Per-frame submission that advances and draws one GPU particle system.

Submit on SceneFrame::gpu_particle_systems. The renderer dispatches an emit kernel that spawns new particles into the persistent buffer behind system_id, then a sim kernel that integrates forces and decrements lifetime, then draws the live particles through the render route chosen when the system was created. No CPU per-particle work happens on the host.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

system_id: GpuParticleSystemId

Target system. The buffer behind this handle is updated in place.

emitter: EmitterConfig

Emitter parameters for this frame’s emit pass.

forces: Vec<ForceField>

Forces applied to every live particle this frame.

time_step: f32

Simulation time step in seconds. Typically the frame delta time.

settings: ItemSettings

Per-item render settings (visibility, picking, selection).
