We run an O2 with CRM graphics and a R10000 with Performer 2.0 and IRIX
6.3. We run a performer application that simulates an industry environment
where the user is able to put on helmets and gas masks.
The problem is that performer sometimes doesn't draw the whole area of a
triangle, if the triangle seems to be bigger than the screen (maybe a
clipping problem?)
For example, if the user wears a gasmask, the mask, consisting of
transparent polygons, covers the whole screen. The scene behind it is
visible of course because the mask is drawn transparently. Sometimes,
parts of the mask are not drawn. But not a whole triangle is missing, but
only triangular parts of a triangle, where one side of that missing
triangle is the screen's border (that's why I assume it is clipping bug in
the graphics library).
Has onybody heard before from this bug, or has even fixed it?
Thanks in advance,
Uwe Pachler
