Hello Again.

We have an application in which we use the pfSegSet to determine the
height and normal of the terrain. When we run this application on
either our Onyx iR (2RM) or our Indigo2 Impact the intersections work
fine for all of our databases.

However, we recently had to run this application on an Onyx2 iR (2RM),
and so, to help the port, I statically linked our application to the
Performer libraries on our Indigo2 Impact.

When we run one of our databases with this performer application on
the Onyx2, the pfHits and pfSegSet work fine (hits returning greater
than 0).

But, when we run the same application with a different database, the
pfHit count returns 0.

I'm confused by this behavior since the application and all databases
give the correct height and normal values when run on our Onyx and
Indigo2. Any ideas as to what might be causing this?

(We do not have the option to recompile on the Onyx2 - also, just for
your knowledge, I did try our application with dynamic linking, but we
had the same results).

Pete
