When Grass Mania became quite a big project and compilations started to take a while, I found it hard polishing the game. For example, configurating lighting without a level editor or a tool was really time consuming. This forced me to write this simple tool which I used for a while. It also serves well as an OpenGL basic lighting tutorial.

This is a very simple interactive program. The user can load a certain Cal3D or OBJ model and light it up. The user can get a view of the model from any angle and change all the possible basic lighting parameters for one that OpenGL has for one light.
