<br>
In the application I am developing I need to implement sub-selection, that is picking of the elements that compose a drawable. e.g. for a mesh, that would be selecting / picking the vertices or triangles that compose the mesh. For instance, this makes it able to edit the mesh by updating its vertices position.<br>
<br>
Is this possible to achieve with OSG?<br>
<br>
What I have seen so far in OSG (i.e. LineSegmentIntersector and PolytopeIntersector) only returns the drawable, and it does not seem possible to return the vertices or triangles  composing the drawable.<br>
<br>
Kind regards,<br>
