not directly. The interesting question is what you want to use it for.
If you need it picking/selecting points/lines there is an example in
Source/WindowSystem/GLUT called testLineFrustumIntesector.cpp that you
might be able to base it on. It iterates through a geometry and selects
all the edges that intersect a frustum (i.e. an area of n pixel around a
click point).
We don't have a full-blown demo for that, but that test might help you
get started.
Hope it helps
Dirk
