Struct SwarmScene 

pub struct SwarmScene { /* private fields */ }

~10k-particle CPU flow-field swarm, driven by named preset parameters.

Implementations

impl SwarmScene

pub fn new( device: &Device, surface_format: TextureFormat, particles: usize, ) -> Self

Build the pipeline, buffers, and seeded particle set on device. particles is the active tier’s swarm_particles. The count is fixed for the life of the scene — the instance buffer and the CPU mirror are both sized to it here, so the per-frame path never allocates — and a tier change rebuilds the scene rather than resizing it.
