Show HN: Rotating torus in terminal (but with kitty graphics protocol) (andreadimatteo.com)

24 points by deotman 1mo ago ↗ HN

Hi HN,

I'm taking Computer Graphics @ Stanford this summer and wanted to express some very simple concepts I had in mind. That's why I wrote a rotating torus in C. Going from writing a ray-tracer that works in Blender to pure C with no dependencies feels relaxing. Wanted to try Kitty Graphics Protocol on the way, rendering images in terminal felt cool.

Open to comments and suggestions.

The torus.c file start with this include directive.

  #include <_time.h>

I'm not sure what that header file is, but commenting it out allowed for a clean compile for me

Man I love toruses/tori

For those inclined to multivariable calculus, do your dopamine crow brain a favor and set pencil to paper.

It's super-intuitive because everything's a circle. The equation for calculating volume is beautiful, and figuring it out is fun.

Just thinking about a wave equation for the graphic is interesting
