I am creating a software to control 3D avatars. I was hoping I could get some help from the ones used to this stuff and working with graphic engines. I have some doubts:
1) What information do you usually need to get the Avatar working?
angles rotation, matrix rotation, quaternions? or anything else?
2) What graphics engine are most used?
3) I've been working with irrlicht, and its proving to be quite challenging... Any complaints or warnings regarding this engine?
Thank you a lot!
