Toy project to develop a 3D rendering project and learn git.
Seriously, read https://github.com/mearns/raytrace/wiki/dependencies
You'll need to download the gtk+ 2 dependencies: http://www.gtk.org/download/win32.php
The 'All-in-one' bundle for GTK+ 2.x is suggested, it has all the tools and libraries required. http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.24/gtk+-bundle_2.24.10-20120208_win32.zip
You'll need to set paths appropriately to build & run the raytrace application.
