Closure plots

Simple script written for our SoME4 video submission to render closure plots of any number system.

Look at the example closure plots shown in the video in more detail here.

You can pass any type that implements the Float trait into closure_plot_3d(). The operation to plot the closure can be changed to whatever you like. You could plot complex formulas, though you might need to change the number system to something more precise than 64 bit floats (like 128 bit floats, or even astrofloats).

Usage

Run cargo run --release --bin image in your terminal to generate some images.

You can change the image file path, the resolution, closure operation and data types to be compared inside src/bin/image.rs.

Info

At the highest resolution of 16, images get too big to open with a regular image viewer, so you might want to convert them into Deep Zoom Images, or a comparable format. Also, my code takes up about 80GB of RAM on the highest resolution. I could probably reduce this to around 12GB if I refactored some stuff, but this was really only a one-off script for the video, so I don't see the need for that right now. If you want to use my code and you need it to be memory efficient, open an issue. I'll try to fix it as soon as I get the time.

The plots are parallelized using rayon and take about 5 seconds to run on highest resolution on our uni's compute server. If you don't want that, change the .par_iter() inside the closure_plot_3d() function to .iter().
