Problem with glCopyTexSubImage3D

I want use the glCopyTexSubImage3D function, but the thing that is in the texture after the call isn’t the same that in the screen.
I have a correct display on the screen, but on the texture I can see only vertical lines, as if the picture was vertically stretched… Do someone has an explication ?
I use it calling :


where “x” is the zoffset and “Dim” the dimensions of the 3D texture…

Finally it’s OK !
I installed a new driver and everything is like it should be ! (Grrr… All this time lost anly for a problem of driver… And the old one wasn’t so old : I changed it only a month ago…)

Have you checked

  • glReadBuffer?
  • glTexParameter (mip mapping off)?
  • if 3D textures work if you download them normally?

PS: I wrote too slow.
