class simvx.graphics.renderer.particle_pass.ParticlePass(engine: Any)¶

Renders particles as camera-facing billboards.

Each particle is a 6-vertex quad (2 triangles) expanded in the vertex shader. Particle data is uploaded to an SSBO each frame.

Initialization

setup() → None¶

rebuild_pipeline(render_pass: Any) → None¶: Recreate the particle pipeline against a different render pass (e.g. HDR).

render(cmd: Any, particle_data: numpy.ndarray, view_proj: numpy.ndarray, camera_right: numpy.ndarray, camera_up: numpy.ndarray, extent: tuple[int, int]) → None¶: Record particle draw commands.
