Forma Fractalis - Free GPU-Accelerated Fractal Explorer in Rust

Features

12 Fractal Types

Mandelbrot, Julia, Burning Ship, Tippets, Multifractal-Julia, Cactus, Marek Dragon, Tetration, Lemon, Zubieta, Sin Julia, Insideout Dragon.

GPU-Accelerated Rendering

Real-time fractal rendering via WGPU compute shaders for 7 fractal types. Tiled GPU rendering handles large exports without running out of video memory.

High-Precision Deep Zoom

CPU high-precision mode using arbitrary-precision BigFloat arithmetic at 64 to 1024 bits. Zoom past 10^15 magnification without banding artifacts.

HSV Color Picker

Interactive saturation-value plane and hue bar. Hex and RGB entry. Custom gradient editor with draggable stops.

8K Export and Animation

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.

CLI and Batch Rendering

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.

Quick Start

            # Option 1: Pre-built binary (Windows)

            # Download from Releases page, extract, and run forma-fractalis.exe

            # Option 2: Build from source

            git clone https://github.com/ConociendoAlmasMenosHastiadas/forma-fractalis.git

            cd forma-fractalis

            cargo run --release

            # CLI rendering

            forma-fractalis render -i settings.json -o output.png --width 3840 --height 2160
