orxonox/trunk: so, ResourceManager now operates on BaseObjects. If this is better, i do not know, but at least it is more intuitive, i think

2 * @file md2Model.h
3  *  Definition of an MD2 Model, a model format invented by ID Software.
4
5    We are deeply thankfull for all the wunderfull things id software made for us gamers!
6
7    The md2 file format is structured in a very simple way: it contains animations which are made out of
8    frames (so called keyframes). Each frame is a complete draweable model in a specific position.
9    A frame is a collection of vertex and its compagnions (normals, texture coordinates).
10
11    A typical model has about 200 frames, the maximum frame count is fixed by MD2_MAX_FRAMES to currently
12    512 frames. The maximal vetices count is set to 2048 verteces, not enough?
13    You just have to change the MD2_MAX_* values if it doesn't fit your purposes...
14
15    Surface Culling is fully implemented in md2 models: quake2 uses front face culling.
