:Some CADCentre-like companies would like this feature so they could use all of
:Performers MP, Culling etc.... while rendering their data from parametric
:cylinders,spheres etc.... You can change complexity on the fly from parametric
:geometry & also save loads of memory. So I disagree with my previous terse
:comment.

I'll also add that IRIS Performer2.0 includes support in each geoset for a
user-defined draw callback. Setting this to your "draw a procedural shape"
function and having the data for that shape referenced in the geoset's user
data pointer allows exactly this. It's something we added the day after we
saw the CADCentre demo.

We're always open to good ideas.

Michael.
