Title: GeometryUpdater

Hi,         IMHO, GeometryUpdater provide a way to allow user to update the     geometry dynamically and efficiently by the following reasons:     1. Thread safe. (Java3D is rendering on its own thread).     2. Efficiency. I believe that attach/detach a live scene on the BranchGroup         is relatively slow. If the Geometry object you are trying to update is         under a big BranchGroup, the overhead would be even bigger!     3. ...       There might be other reasons that people can provide in this group.     There is a sample program in Java3DTutorial/animation that demonstrates     how to use GeometryUpdater. You might want to check it out.   Scott ----- Original Message ----- From: Smith, David To: [EMAIL PROTECTED] Sent: Monday, February 24, 2003 11:36 AM Subject: [JAVA3D] GeometryUpdater I am not sure I fully understand the purpose of the GeometryUpdater. If I modiy the GeometryArrays on Shape nodes, I can either recreate, or modify existing ones.  Either way, I usually just detach the branch, and reattach it after modification/creation. Could someone shed a little light on the purpose of the GeometryUpdater? Thanks, -DaveS
