RE: [osg-users] help ... white texture bug
Hello, Thanks for the reply. I've tried different texture sizes, so I think texture dimensions do not matter. It's definitely something else. Gilbert, Daniel R.

Re: [osg-users] help ... white texture bug
Hello Robert, Thanks for the reply. We have tried the program on different cards, it has worked on NvidiaFX5600, NvidiaGo7800, Mobility Radeon9200 , but has failed on relatively newer Quadro 1300 and Millenium, amongst other professional cards. Moreover, if we replace the same image with the image used in the example texture2D, the example program works on an intel built-in graphic card on Windows XP, but almost the same code does not work on that machine, when used with Qt or WxWidgets, which leads me to believe that there may be something wrong with the OpenGL (QGLWidget) window initialization (though since the same executable is working on other machines so it can't be the code alone that has the problem). The solution may be relatively simple, but nothing we have tried so far has worked, so I am looking for possible causes of this problem.

Re: [osg-users] help ... white texture bug
Hi Wasi, Everything your report points to driver bugs and such will be hard to pinpoint and workaround. Try to find updated drivers. Robert.
