Hi,

I develop a visualization prog with Qt 2.2.3 and OpenGL under both windows and linux.

I render 3D object with 3 methods :
Wire Mode
Solid mode
Wire and Solid mode

but on some PC, the rendering bugs :

Solid mode
Wire and Solid mode

What is the problem ? I do the same with linux and windows.
It seems depthBuffer is disabled !!!
How can i correct it ?

If the depth buffer works on some pcs and not on others,

1) Make sure you are using up-to-date drivers

2) Make sure the depth buffer bit depth you are requesting is supported, and if it isn''t that you select one that is supported.

3) If you are forced to use lower resolution depth buffers on some pcs, try narrowing the z range (ie push the near clip plane outwards a bit) to see if that helps.

If that doesn''t work, come
