Fractl
- Fractal renderer written in rust
- Singlethreaded, multithreading (using rayon) and gpu compute (using wgpu - WebGpu implementation) versions
- Supports both native targets and wasm
- Currently renders the Mandelbrot set and the Multibrot set
Screenshots
How to
- Try the live demo (Note: the web version runs on a signle thread without GPU acceleration, native version are much faster)
- Download a pre-build binary from ./bin
- Install using cargo (TODO)

To build:
nix build .#Package -
To build and run locally:
nix run .#Package -
Example:
nix run .#gui-gpu -
Or use on of the build scripts in ./script
Building using cargo
- Have rust installed, or optionally use the included dev shelle:
nix develop - Pick feautres
