Hallo,

Iwork with vega and performer and I try to move planes from objects.
With pfNodeIsectSegs and pfQueryHit I detect intersection with the
geoset, primitive and triangle. With pfGetGSetAttrLists I get the
coordinates-list from geoset. Now I can move the correct plane.
(all triangles with the same PF_X-value + or -)

But there are mistakes in intersecting the moved plane. I can only
detect intersection with the old plane (old coordinates).

There are also mistakes in vega's presentation. The clipping don't work
correct. In my opinion the clipping-algorithm works with the old
coordinates or vega has its own clipping-algorithm (I don't believe).

Maybe I need an pfUpdate ?

Thanks in advance for any help.

Maik
