While teaching my OpenGL Bootcamp this week, the realization hit me that the standard pictorial representations for the viewing volume generated by using glFrustum() simply weren't descriptive enough for my students to really get it.

That prompted me to make a little frustum helper application which visualizes the results of changing the values of glFrustum(). Since it helped my students a bunch, I figured one or two beginners here may find it helpful as well.

Here it is if you want to play with it:

This is fantastic! I'd really love to see a whole suite of applications like this for understanding the various maths of OpenGL...
