DisplaySprite3D and clipping

andreyu · Post by **andreyu** » Mon Oct 02, 2006 12:53 am

How to make clip for CreateSprite3D? I wish to place many fragments on one texture (animation for one object on one texture, for example) because texture switching is slow.

This is not good for me because this code utilize DirectX. I need cross-platform solution.

Bad news...

Sprite3d is windows only.. Because it's DX based...

Correct me if I am wrong, but isn't that only true if you are using DX. With 4.0, if you are using the OpenGL subsystem, doesn't Sprite3D use OpenGL and won't it be cross-platform as soon as the Linux & Mac versions of 4.0 appear?

As i know linux version should support Sprite3D in future. But linux does not support DirectX.

Fred, may be you can help me? Or, may be, you plan to add this functionality?
