The necessary steps to use a shader in an OpenGL application are discussed in some detail. Since no new ressources is used in each loop, the memory is going to stay stable. Source Code Trouble Shooting: Before writing shaders, in any language, it is a good idea to understand the basics of the graphics pipeline. In this tutorial shader programming using GLSL 1.

Shaders are a hot topic and 3D games have shown that they can be put to good use to get remarkable effects.

OpenGL does not manage keyboard and mouse type of devices. This dual coverage is prone to mistakes, so please let me know if you find something wrong.
