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

Ok, thanks, it works, but when i set the near clipplan far, it cuts my object !
Before (without the ok) the near clipplan = 0.1, it was ugly, now it’s 0.5, te render is better, but object are clipped ! what is the best value for the near plan ?
A good value for the near plane is about 0.1% of the far plane. You can go down to 0.01% for a 24-bit depth buffer. Example; if the far plane is at 10, you can have the near at 0.01. If The far plane is at 10000, you can have the near at 10. It’s not absolute values that matter, but relative values.
