Hi scott, hmm... how did that help?? mesh.pushback just sets a z-sort method, and it didn't work for me. I am just trying to hide individual segments within a mesh and it seems visible=false is just ignored. If this is not possible, tell me where to look in the source. I'm willing to hack it.
I'm doing a manual clipping function, so i guess in a sense I am doing z-sorting. see what i'm doing here and give it 15 seconds to load. This is with the OLD LineSegment render method - so it works the way I want it to, but too slow. http://www.baslerdesign.com/location/lines.swf
