miniRT

miniRT is a project from the 42 Common Core, The project aims to build your own raytracer from scratch in C.

Usage

~/shell$> make
~/shell$> ./miniRT example.rt

To use CUSTOM texture maps (must be in .xpm format)

~/shell$> ./miniRT example.rt example_texture.xpm

To use CUSTOM texture maps + bump maps (must be in .xpm format)

~/shell$> ./miniRT example.rt example_texture.xpm example_bump.xpm
