Fast PBR Particles is a mesh-based particle system that generates its geometry once and then evaluates all particle behaviour entirely in the shader, enabling cinematic effects with minimal CPU cost and excellent platform coverage.

Core principles:

• Minimal CPU workload: particle meshes are built once; there is no per-frame CPU simulation, all temporal evolution is evaluated on the GPU with single-draw-call rendering.
• Broad graphics API support: despite the simulation happening on GPU, it doesn’t require any advanced features targeting nearly all mainstream graphics APIs including OpenGL(ES) 2.0, DirectX 9.0, and all modern API. while preserving the same feature set.
• Physically based imaging: motion blur, depth of field, inter-frame temporal control, and exposure are derived from physical optical phenomenons with strict energy conservation.

Features:

• Physically based motion blur from shutter interval by stretching the particle footprint (no post-process required).
• Physically based depth of field: bokeh radius derived from physical camera paremeters or volumes.
• Energy conservation: fixed per-particle energy over the shutter interval.
• Temporal controls: between frames blending, closed shutter interval, turbulence.
• Lit and emissive particle shaders.
• Deterministic playback and time reversal.
• Acurate trajectory integrals accout for gravity, drag and wind.
• Static lights mode: bokeh + camera motion blur for non-moving light points.
• Made to be extended.

A fullscreen camera stylisation effect that splits the image into distinct color bands and fills the transitions between them with tileable patterns. The light position of each color band is individually controllable, giving artists precise creative control over the resulting look.
