There are no problems using SDL! As I said We already use it, but there is still a glest abstraction layer used yet , which has to be eliminated ....

I once tried it a bit just for fun with the jmonkey engine:

I was able to load/show g3d models including animations too, but I was facing too much work, so I gave it up.
