Hello Martin,
I try to render in a texture with osg. And it works. I thougth that is
no problem. I have a NVIDIA GeForce 8800 GT. Now I try to start my
program on another computer and it doesn't work. This computer use a ATI
FireGL V5600 graphic card. It seems that the problem is a driver
problem. Have somebody experience about this problem?
Using GLView (cool program that lists extensions available on your card,
and that also has a database of known graphics cards to see which
extensions are avaliable on them - http://www.realtech-vr.com/glview/)
it seems that the ATI FireGL V5600 has the extension required for FBO
support (GL_EXT_FRAMEBUFFER_OBJECT). So I think a driver update should
help. ATI's more recent drivers have generally improved OpenGL support
quite a bit.
Maybe help a driver update? But what can I do when the update doesn't
help? Or there are another way to render in a texture without
frame-buffer-object?
You could use PBuffers. But it will probably be slower.
Normally OSG will fallback to PBuffers if FBOs are not supported, but in
your case it seems like they should be supported but don't work,
possibly because of a driver issue as I said.
Hope this helps,
J-S
