A week ago, I asked about transparency problem when I modifed
motif.C sample program. I did not get any reply and guess my question
was not clear enough to answer. Since then I narrowed the source
of problem, and here I am asking again.
The problem is when I modified motif.C to include my application,
transparency did not work. Actually, it worked between faces
under the same gset, but not between different gsets.
I tracked the problem to the line
Shared->chan->setTravMode( PFTRAV_CULL,
PFCULL_VIEW | PFCULL_GSET );
If PFCULL_VIEW is set, transparency did not work, but when it is
removed, transparency worked find.
Is this a bug, or transparency is supposed to work only between
faces in the same gset. Although I turned of PFCULL_VIEW,
man page says setting PFCULL_VIEW will give better performance.
Is there any way both setting PFCULL_VIEW and making transparency
working?
Thanks for any info.
