I am a beginer on game development. I wont write simple game with DirectX 10 and need to load animation like man playing cards. I don't know how to strat. As I know I must create my own file format and convert from some other format to it, but I don't know how. So please help me and if it is possible give some code example.
The DirectX SDK features a sample application with source code called Skinning10 that implements character animation.
The NVIDIA Direct3D SDK shows off Skinning with Dual Quaternions.
Also, you may want to have a look at the CAL3D Character Animation Library.
