# `wgpu-mandelbrot`
A realtime mandelbrot renderer using [wgpu](https://github.com/gfx-rs/wgpu).
I used this as a practise project to learn some modern graphics fundamentals via `wgpu`.

## Architecture
Pixel [iterations](https://en.wikipedia.org/wiki/Plotting_algorithms_for_the_Mandelbrot_set#Unoptimized_na%C3%AFve_escape_time_algorithm)
and colours are stored in host memory (RAM).
Rough per-frame breakdown:
1. The remaining unescaped pixels are sent to the GPU
1. A compute shader iterates each pixel
1. The results are copied to host-available memory
1. The CPU partitions the results into newly-escaped and unescaped pixels
1. The newly-escaped pixels are used to re-compute the pixel colours
1. The new pixel colours are sent to the GPU
1. A fragment shader colours each pixel
