omg - Open Machinery for Graphics

omg is a library for computer graphics applications that provides some executables, like a ready-to-go raytracer that uses YAML scene descriptions to produce 3D images.

omg uses tao, a mathematical library written by the author. Caution: it is not optimized yet, but works well.

Learn how to use omg by reading the docs!

./raytracer <path to .yml file> <image destination>
