orxonox/branches/md2_importer: now created all the structures needed to load a md2 file. there are some types that have already been defined in other files of orxonox. i will use the original md2 structures. there is time for cleanup and resolve possible conflicts later: as soon as md2 works

File:

• orxonox/branches/md2_loader/src/lib/graphics/importer/md2Model.h (modified) (6 diffs)

         We are deeply thankfull for all the wunderfull things id software made for us gamers!
 
+        The md2 file format is structured in a very simple way: it contains animations which are made out of
+        frames (so called keyframes). Each frame is a complete draweable model in a specific position.
+        A frame is a collection of vertex and its compagnions (normals, texture coordinates).
+        
+        A typical model has about 200 frames, the maximum frame count is fixed by MD2_MAX_FRAMES to currently 
+        512 frames. The maximal vetices count is set to 2048 verteces, not enough?
+        You just have to change the MD2_MAX_* values if it doesn't fit your purposes...
