## What it is
PixelFlow is a Processing/Java library for high-performance GPU computing via GLSL shaders. It provides fluid simulation, flow-field particle systems, softbody dynamics, a realtime Skylight renderer, extensive postprocessing filters, and antialiasing techniques.

## Use cases
- simulate real-time fluids in Processing sketches
- create GPU-accelerated particle systems with flow fields
- run cloth and softbody physics simulations
- apply postprocessing filters like bloom, blur, and optical flow
- render scenes with ambient occlusion and soft shadows
- run Shadertoy shaders inside Processing

## When to choose
- you use the Processing IDE and need GPU-accelerated simulations or visual effects
- you want fluid, particle, or cloth simulation in Java with GLSL performance
- you need a broad set of image-processing and postprocessing shaders in one library

## When to avoid
- you are not working in Processing/Java
- you need a maintained library with recent releases (last release was 2018)
- you need CPU-only simulation or headless server-side rendering

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, simulation, image-processing, gpu-computing
- domain: graphics, simulation, computer-vision
- platform: jvm, cross-platform
- tags: processing, glsl, fluid-simulation, particle-systems, softbody-dynamics, optical-flow, postprocessing, antialiasing, shadertoy, opengl, physics, game-development, creative-coding, desktop, gpu
