[Plib-devel] directional lights

[Curtis L. O. <cu...@me...>]

Steve,

Does plib provide any facilities for drawing or not drawing an object
based on relative view angle?  I'm pondering how I might impliment
directional lights such as VASI for runways ... lights that change
color depending on your relative angle to them.

Thanks,

Curt.
