This teaches you how to animate Quake3 character models (.md3) using key frame animation.  This is done through linear interpolation of vertex key frames, as well as spherical linear interpolation (SLERP) for bone and joint key frames.  Quaternions are introduced for the first time in conjunction with character animation.

Functions Used:  fopen(), fclose(), fread(), fseek(), ftell(), strcpy(),  SwapBuffers(), gluLookAt(), glVertex3f(), glBindTexture(),
glTexCoord2f(), glEnable(), malloc(), free(), GetTickCount(), _stricmp(),  vector::push_back(), vector::clear(), new, delete
