Ok, now I understand better. You can still use 1 TriangleArray holding all your geometry. Better, BY_REFERENCE, and then you update it with a GeometryUpdater. That ensures that the whole geometry will be consistent. And, considering what you're doing, the fastest option.

The simulation includes particles of different arbitrary geometries (shapes with n-sided polygonal convex faces) and the orientations change from frame to frame. Instead of dealing with a large number of TransformGroups I just recreate the geometries for each frame. -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of T.J.Hunt Sent: Friday, February 20, 2004 8:29 AM To: [EMAIL PROTECTED] Subject: Re: [JAVA3D] Shape3D problem From: Ibrahim Z Mohammad [mailto:[EMAIL PROTECTED] > The problem is, since > I have a very large number of geometries (around 30,000, I'm > doing visualization for a granular soil particle simulation > where each geometry is a soil particle), the geometries don't > appear at the same time, rather the renderer starts by > rendering the geometries one by one, from the first added one > to the last. Why not use just one geometry, which is a PointArray with 30,000 points in it, and instead of adding and removing the Geometries, just change the coordinates of the points in the array?
