Opengl draw distance cutoff
Oct 5th, 2007, 3:24pm  
Hi all,

I'm developing a sketch that involves moving objects very far away, However once they get past a certain distance from the camera, they dissapear ... They are very simple shapes(just a bunch of planes) so there is no need to stop drawing for performance reasons. is there any way to set the maximum distance for opengl?

Thanks in advance.

Your far clipping plane needs to be extended. Also, when you extend the far plane like that, you might want to do the same for the near clipping plane- if opengl is viewing a large area, like .001 to 10000, you'll probably see artifacts.
