I'm trying to create code to (roll, tumble) dice in 3D.

However, the instructions that I use (RotateMesh, TurnMesh) both work in such a way :

Stand in the center of an object, spin the object around you like the earth revolving around the sun.

I don't want that kind of motion, but the type of motion I do want is when a person throws a dice onto a board!

you have to move the camera a bit backward, to stand outside of the object:

Graphics3D 800,600
dice=CreateCube()
camera=CreateCamera()
light1=CreateLight(1)

MoveEntity camera, -3,3,-5

Repeat
     TurnEntity dice,Rnd(3,4),Rnd(3,4),Rnd(3,4)
		TranslateEntity dice,Rnd(-0.1,-0.2),0,Rnd(0.2,0.3)
		UpdateWorld
		RenderWorld
		Flip
Until KeyHit(1)

you dont have to be wealthy to have knowledge.

Do you mooch off of your girlfriends?

I fail to see what that has to do with ANYTHING!

but in general ask and you shall recieve as long as its reasonable and wont take much time.

That's the joy of sitting in front of the screen staring at code... it costs nothing :) (alright, save for the electricity bill)

But yeah, on creation, all the entities in B3D are created at 0,0,0 world-coords, including the camera, so it's always best to move the entities or camera right away :)

You could improve it even more by using a Physics library (don't ask me which one =X ), because that would cause the dice to really spin around the point of collision with the table or whatever (like it happens in real life).
