fractal_rs

This is a port to Rust of my implementation of rendering a Mandelbrot set written long long time ago in C++.

Running

cargo +nightly run --release

Navigation

• Left mouse click Centers view on given position
• [ Zoom out
• ] Zoom in
• ←↑↓→ Fine tuning, moves the view by 10%
• = Increase iterations
• - Decrease iterations
• 1...9 Set center of the window to some POI (6 is iteresting one)
• 0 Reset view
• space Dump current position to the console

Features

• simple version - one thread + double
• multithreaded - unsafeCell + atomics to sync up with workers
• multithreaded using Rayon
• avx2 version + Rayon
• avx512 (lack of CPU to test it, lol)
• arbitrary precision rug
• quadruple (double double) + Rayon:

• Use builder and strategy patterns to conveniently select fractal, point on a plane, floating arithmetic, and the executor.
• arbitrary precision custom SoftFloat
• arbitrary precision ramp
• cuda?
• try to improve rug execution?
• using new algorithm to calculate

• Julia
• create a video from the pass
• adaptive float type selection on the fly
  • start with the floats, jump to doubles, then go to quads. Depending on the zoom magnitude.
• port to WASM
