/usr/share/Perfomer/src/pguide/libpf/motif.c
on an IR system and had some wierd results. It appeared that the
z-buffering was not working correctly. For instance, when looking
at the blimp.flt model, you could still see the gondola even when
it was rotated so that it was on the far side of the blimp. You
could see the same behavior with the fins on the blimp as well.
I tried another program I wrote and saw the same behavior. The
programs are rendering into a GL widget that was created as follows:
_glwidget = XtVaCreateManagedWidget ( "glwidget",
glwMDrawingAreaWidgetClass,
_frame,
GLwNrgba, True,
GLwNdoublebuffer, True,
GLwNallocateBackground, True,
XmNwidth, 707,
XmNheight, 707,
(XtPointer) NULL );
Any ideas?
