Fractal Generation App

This is a simple Rust application made with Druid which provides the tools to create complex fractal images. It uses a highly-performant multi-threaded and SIMD-enabled backend to compute fractals in near-real-time on the CPU.

Compiling

Currently, the backend works best when the target feature avx2 is available, as this enables SIMD operations.

# debug [non-release] builds are significantly slower, useful for development only
cargo build --release

Running

cargo run --release

TODO:

• Current implementation of progressive rendering doubles the amount of work. Pixels which are already calculated should not be re-rendered. This could be done by scaling only the height to allow SIMD execution to work normally on the width of the image.
• The render tab needs an aspect-ratio corrected render preview. This will require a controller for the size of a container around RenderView.
• The info text at the bottom of the settings pane should be more fully utilized. This is probably best implemented with a ExtEventSink.
• I would like to add support for the Newton Fractal, in addition to MandelBrot and Julia. Other fractals are possible as well.
• LONG TERM: Precision could be greatly increased by utilizing abitrary-precision floats and perturbation.
