A free, open-source fractal explorer built in Rust. GPU-accelerated rendering, 15 fractal types, perturbation-theory deep zoom, and professional 8K export.
v0.2.7 Showcase — Mandelbrot deep zoom beyond 1040 magnification, rendered via perturbation theory at 3840×2160 (2× Lanczos3)
Mandelbrot, Julia, Burning Ship, Tippets, Multifractal-Julia, Multi-Julia IFS, Cactus, Marek Dragon, Tetration, Lemon, Zubieta, Sin Julia, Insideout Dragon, ChaosSymmetry1, and Lace Julia.
WGPU compute shaders cover the GPU-ready escape-time fractals, while dedicated orbit backends accelerate select attractor renders. Tiled GPU rendering handles large exports without running out of video memory.
CPU high-precision BigFloat rendering and Mandelbrot perturbation theory work together for extreme zoom workflows, from exact fallback rendering to reference-orbit acceleration.
Interactive saturation-value plane and hue bar. Hex and RGB entry. Custom gradient editor with draggable stops.
Export fractal renders up to 8K resolution as PNG with Lanczos3 downscaling. Create animated zoom GIFs. Every exported file embeds full rendering parameters as metadata.
Render fractals from the command line without a GUI. Batch process export jobs, override parameters, and save or load settings as JSON for reproducible workflows.
Forma Fractalis is maintained by one person in their spare time. It is free, always will be, and has no premium tier, no ads, and no telemetry. If you have found it useful and want to help keep development moving, a small donation goes a long way.
