[gameprogrammer] Re: Pseudo-sky

["Kevin Fields" <drunkendruid@hotmail.com>]

It's being drawn, and well within the far clipping plane.
I set the far plane to -1000 and I'm drawing the sky at -100.
I actually was able to come up with a quick fix, which seems to work for 
now...
I have my Terrain Manager, which uses an Update function. This function 
takes in a pointer to my camera class. I plan on using quadtrees later on. 
Anyway, what I do is get the position of the camera, and I subtract 100 from 
the z-value of the position. This happens each frame, so the sky will always 
appear in the background.

It's crude, I know, but it works for now.

It isn't showing up at all? My guess is that you are drawing it behind
the far clipping plane and it is getting clipped out.
