A simple raytracer written in C.

Raytracer

A simple raytracer in C, with diffuse and specular lighting, reflections, shadows, environment map, and a couple other features. Developed following the tutorial "Understandable RayTracing in 256 lines of bare C++" and "Ray Tracing in One Weekend".

(Converted from ppm to png.)

Building and Running

Currently, the program takes no arguments and outputs the image directly to stdout (in PPM format).

$ git clone --recurse-submodules # required for the libs
$ make
$ ./raytracer >out.ppm # or ./raytracer | display

You can change the rendering parameters at config.h.
