Detailed Description

This namespace contains the lower part of graphics rendering architecture of Teddy. Other parts are in several other modules; you should at least know that PhysicalComponents module has Projection class, which is responsible for applying materials and rendering any 3D graphics.

While some parts of OpenGL have been encapsulated into View class in Graphics, there are still a lot of direct OpenGL calls all over Teddy. In the future all OpenGL should be made through encapsulated interface.
