/*
|
||||
* Here are the definitions for Ravensoft's model format of md4. Raven stores their
|
||||
* playermodels in .mdr files, in some games, which are pretty much like the md4
|
||||
* format implemented by ID soft. It seems like ID's original md4 stuff is not used at all.
|
||||
* MDR is being used in EliteForce, JediKnight2 and Soldiers of Fortune2 (I think).
|
||||
* So this comes in handy for anyone who wants to make it possible to load player
|
||||
* models from these games.
|
||||
* This format has bone tags, which is similar to the thing you have in md3 I suppose.
|
||||
* Raven has released their version of md3view under GPL enabling me to add support
|
||||
* to this codebase. Thanks to Steven Howes aka Skinner for helping with example
|
||||
* source code.

||||
