    ATI Radeon 7500 and texture wrapping

    Hi...
    With my new notebook I'm seeing some artifacts at the borders of textures: in particular, when I want to GL_CLAMP the values (like it's good to do in skyboxes, for example). This app ran fine with a lot of other machines.
    What I see is a dark line at the edge that with my old pc I haven't ever seen.
    I'm sure some post talked of it but I wasn't able to find it, and it seemed that it was a matter of video card...
    Someone can help me?
    Thanks in advance!

    You can give your texture a border, or set its wrapping mode to to GL_REPEAT or GL_CLAMP_TO_EDGE.

    You may have to do a #defile GL_CLAMP_TO_EDGE 0x812F before GL_CLAMP_TO_EDGE will work.

    Thanks a lot!
    That was what I needed!
    But... where can I find an updated gl.h without defining other GL_stuff ?

    Why do you need to defile GL_CLAMP_TO_EDGE? What did it ever do to you!?
