Detailed Description

Abastract base type for geoemtric primitives.

Primitives are atomar geometric entities, that are used to build SceneObjects. Primitives must only* define, how they are rendered in OpenGL. For rendering, the primitives can access the parent objects data such as vertices and normals. By these means, several primitives can share resources such as vertices, normals or even textures. Usually primitives will just define vertex indices that are then used to pick the correct vertices from the parent SceneObject's vertex list.
) only is not completely correct, they also have to implement a deep copy interface
