<DIV><FONT face=Arial size=2>I use spheres to represent multiple seismic events
with one actor. I get around picking by using a programmable glyph filter and
building a lookup-table based on cell-ids on each iteration of the GlyphMethod.
When you do a pick on the actor you can then get the id of your input point from
the id of the picked cell.</FONT></DIV>
