We don't do anything fancy in our application yet; no stencil
planes, no antialiasing, and no manual use of the polygon offset
extension.
The problem is concisely shown in this example from the Performer
2.2 MR.
If you compile /usr/share/Performer/shadows.c from
/usr/share/Performer/src/pguide/libpf/C with the following
command line:
cc -o shadows shadows.c -lpf -lpfdu -lpfutil -lGL -lGLU -lX11 -limage
(we're using the 7.1 compilers patched up to #2072, on an Onyx2
iR running Irix 6.4), and then run the executable by
shadows stool.flt
(where stool.flt is in /usr/share/Performer/data), then there
will be two "blips" as the shadowed light does its orbit; the
shadow suddenly turns into a big black box for a moment. Those
blips look exactly like what I'm seeing in my application.
We have a support contract; should I be reporting this problem in
some other venue than here?
Thanks,
-Ken
