Hi all,

I am having problems with Performer rendering my scene incorrectly.
Geometry which is behind other geometry is being drawn on top of the
closer objects. In other words, a box positioned 2 km away from the
viewpoint is being drawn on top of a box only 1km away.

I create the geometry by adding a node containing geometry as a child
to a pfSCS. I create this SCS with a matrix that I have scaled,
rotated and translated. A section of the code follows. By the
way, I have Performer 1.2, IRIX 5.2 and an Onyx with RE.

geomNode = (pfNode *)LoadFile("file.dwb", NULL);

for (i=0; i<numPts; i++)
{
/* creation, scaling, rotating, and translating of matrix done here */
  segment[i]=pfNewSCS(matrix);
  pfAddChild(segment[i], geomNode);
}

Any help will be appreciated.
