[Freeglut-developer] Glut peculiarity?

[Rick C. H. <fox...@ya...>]

I'm running freeglut on ubuntu 10.04.  I had set this up in my app:

gluLookAt(gfViewX, gfViewY, gfViewZ, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0);

If I had gfViewX set to 0.0, then I could not use any value for gfViewY
that would display anything, though values for gfViewZ worked.  If I
chaned gfViewX to 0.01 even, then any value I used for gfViewY works
fine.

Is this a freeglut issue?  Why can't this X value be 0.0?  Thanks.
