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.
Regards
+Wasi

Hi,
On the machines that the texturing don't work it would be worth
checking to see if the TextureRectangle extension is supported. What
hardware is that doesn't work? Do you get any errors?
Robert.
