Hi there,

I'm just implementing a possibility to pick single vertices in my application.

My plan:
traverse the Performer tree by my own,
extract all geodes,
extract all geosets from each geode
extract GS_COORD3 attribute from each geoset
check coords. (considering transformations in path to geode)

What I'm a little bit afraid about is the variety of different primitives
(indexed or non-indexed) and

A possibility would be to check bounding spheres, also, to optimize traversal.

Any other ideas/any comments?

pfGreetings,
Dirk.
