A raytracer in C. It has shadows, reflections, lightning (phong model). You can build it with CSFML 2.0 or libPNG.
You could use included xcode project, or use a makefile located in raytracer directory. If you have CSFML 2.0 installed, then use make with_csfml, otherwise use make with_libpng (use apt-get or brew or whatever to get libpng).
It has 3 hardcoded demos, you can edit scene.c to change them.
For instance:
./raytracer teapot
Have fun.
