Hi pfFriends,
I'm using:
Redhat Linux 7.2
Performer 2.5
My real time application uses pfLPointState to display (successfully) lights
on my scene. The problem I have is that I need the lights to only appear
between certain angles. I have been looking at the documentation and it
says :
Light point direction is defined by the normals (PFGS_NORMAL3) supplied by
PFGS_POINTS pfGeoSets.
This doesn't mean a lot to me so where do I learn what this means and how to
define it. Any pointers to further documentation about how to define the
angles (and halfangles) would be very much appreciated.
Thanks
Rob
