Bevy Firework 🎆

Bevy firework is a particle system plugin where particles are simulated on the CPU and use GPU batching for rendering. This allows each particle system to be rendered in a single draw call (rather than one per particle).

While not as fast as a pure GPU-based particle system, this provides a massive speed-up from the naive approach to CPU-based particles (making it possible to render tens of thousands of particles without noticeable framerate drops) and maintains much of the flexibility of CPU-based particle systems (e.g. easy access to physics data for particle collision, simplified particle system animation).

Current features

Billboarded particles.
Configurable integration with Bevy's PBR rendering (i.e. particles can receive
shadows, are affected by fog and lighting changes).
Particle collision with arbitrary avian colliders.
WASM and WebGL compatible.
Soft particle edges.
Animated properties: certain parameters can be defined as a custom curve to
express changes over a particle's lifetime:
- Scale
- Color
Randomized properties: certain properties can be randomized, so that they are
randomly sampled for every particle:
- Particle lifetime
- Initial linear velocity
- Initial radial velocity
- Initial scale
Emission shapes:
- Point
- Disk
- Sphere
One-shot emission mode, or continuous emission.
