3D bounce ball game

Hi all,

I have to do for my school project game (simulation), where at the beginning user throws ball and it will be bouncing for example in cube.
When ball finishes bouncing, user can play next level.

I am absolutly newbie in OpenGL and we dont have eneough time to do this.
I want to do this in Java with OpenGL libraries.

Can anybody help me please? I will be grateful for any advice.

I am not familiar with Java OpenGL libraries, but I think just the same calls in Java language gramma. But your problem seems most difficult in bouncing calculations which is of mechanics not merely 3D rendering.
