Hey guys,
thanks for your help. Everything worked out fine so far. I'm able to click on
an Objects triangles and mark them with a transparent material by creating a
new node and adding it to the scenegraph, like described in the OpenSG 1.8
Geometry Tutorial.
My Problem is, that somehow the newly created node is not really a new Object.
When I read out the center Point of the Original's Volume and compare it to the
center Point of the marked Triangle, they are exactly the same. So I assume
they still kind of "belong" to each other.
What I need is, that the marked triangles become a seperate Geometry with their
own bounding volume.
Is that possible?
Thanks, in advance

Hi Andy,
You will probably find these references helpful when creating geometies in
OpenSG 1.8

Good luck,

yes, but they only changed names from what they were called in 1.8.

yes, that is the 1.8 equivalent.
