Cinema 4D Version: 10.1&11
Platform: Windows ; Mac OSX ;
Language(s) : C++ ;
in my plugin, I create a clone of a geometry and triangulate it (internally in my plugin, the user doesn't see it).
The user can link Selection tags with polygon selections in my plugin, which he has created on the original geometry.
Of course, when I try to use the user's polygon selections on my internally triangulated geometry, it does not work correctly, since the polygon selection was made for the untriangulated geometry.
How can I triangulate the polygon selection, too, so it fits my triangulated geometry?
Thanks for any help & tips. If more information is needed for answering this, I can provide it.

in cinema if you freeze a selection and than triangulate the object the selection is still there (but only if it has been saved in a selection tag). so maybe you need to clone the selection tag, too?

The problem is, that I don't just use any selection tag that's attached to the geometry. The user links them into my plugin using a LINK field.
This is necessary since the user may have created several selection tags and wants to tell my plugin which of these selections to use.

cant you just select the linked selection and than create a selection tag with that selection on your clone. and after that triangulate it?

Hm, that would be an idea.
I will try that, thanks!

Unfortunately, that does not work correctly...
Using GetClone() I create a clone of the tag and attach it the the cloned geometry (using BaseObject::InsertTag()). After that, I perform an MCOMMAND_TRIANGULATE on the geometry clone to get the triangulated geometry.
But after that, the selection data in the tag is broken. One polygon is always missing: The last polygon in the geometry's Polygon Array. It should be selected, but it is not. All other polygons work fine.
Any more ideas?

Oh wait, stop. It works. Just noticed a problem in the function that selects the polygons of the geometry.
Thanks a lot!
