I would say the union is possible. As for the intersection, I can't see it
happening. Union simply means all of object A and all of object B unite to
make an object C. I have never attempted it, but I think this may work:
Once you have detected that the two objects are coliding, and the user
requests a union, all you need to do is make sure that the two objects
start sharing a transform group so that they'll stick together. What I'm
thinking is that you can create a branchgroup with one TransformGroup (say
utg) as its child. Then detach the two transformGroups (cone and cylinder)
from their Branchgroup and put them as children of utg. Now you can
control the movement of the union by modifying the transform3d of utg.
However, I can forsee exceptions such as capabilities not set, or attempt
to add Branchgroups to live node, etc. You'll just have to be careful.
I hope this helps (and I hope you get it working).
