Hi ,
As a beginner of openscenegraph. I have used a terrain(.flt) as a node,but the
texture data of this node doesn't have alpha value, So I want to create a new
Texture data(with alpha) to replace the exist Texture.At the same time I hope
to copy the former texture data in a different texture unit so that I can use
it next time.
Now my question is how to replace the exist texture with a new texture, and
keep a texture copy in a different texture unit?is there any functions I can
use?
Best Regards!
Judy
