pfHi there,
finally, I solved the problem.
Well, Gordon, the boundings were the problem.
But not of the geosets, but of the geodes and/or DCSes.
The following seems to happen.
I forced recompute of the geosets, immediatly after each change.
Additionally, I forced recompute of the most upper DCS before each isect
because Gordon assumed that incorrect bounding spheres would end up
intersection to early. That was exactly the case.
My assumption was: If a recompute bounding box of a geoset all parent
nodes will notice and recompute, automatically. WRONG!
(At least for fluxed geosets. I didn't recognize something like this
before I used fluxed geosets...)
Now I force recompute of child-DCSes and child-child-geodes, also. And, it
works!
Thanks a lot especially to Gordon and to Christopher and Yair.
pfGreetings,
Dirk.
