I started work on this simple raytracer written as a Haskell package as an introduction to some concepts in computer graphics. It was also a good way to see what makes performance sensitive code fast or slow in Haskell.
After cloning this repository, run stack build and then stack exec example
and an image will be outputted to example.png. The actual raytracing module
is in src/Raytracer.hs and the example scene is in example/Main.hs.
It currently supports spheres and planes, solid colored diffuse, reflective, and specular materials (Phong shading), ambient lighting, and different fields-of-view and light directions.
When running the example, you should get the image below (rendered in 2k):
