I saw this Loading and Animating MD5 Models with OpenGL an old post explaining .md5mesh .md5anim files. Is there any similar alternate mechanisms?
1.) Is there an open source tool or a Plug in for 3ds max to convert a .DXF file to such files which can be used in 3D OpenGL+DirectX game programming.
2.) If I am developing a game in this approach how to make these model files encrypted and make big single file which contains all this file, so that the user cannot crack/hack it?
3.) If I am providing an update via an online gaming server, then how to I update this models and keep it encrypted again?
