[JAVA3D] Updating geometry

I want to be able to send in data to a LineStripArray every so often nad want to update the lines length. I already have it placed in the scene, and want to know if I should just access the same BranchGroup with the shape in it and change its data or should I build a new Branchgroup with the

Jack,   You are correct, the issue of hardware acceleration with Java 3D 1.2 has been discussed, but has not been adequately resolved.   Here is a summary of what is known so far:  This problem appears to be limited to Windows 2000, and not Windows 98 or NT.  On Windows 2000, some graphics cards

I am using LineArray to do what u need. but it will work with any other Geometry. I make a LineArray with maximum coordinates I would need. and then keep setting the coordinates at run time. And it works pretty smooth; private static final int MaxPoints = 200; private int m_nLi

Re: [JAVA3D] Shape3D Performance.

Jean-Marie: There is internal bookkeeping needed to render each Shape3D which results in increase in memory footprint and affects performance when there are several thousand dynamically changing Shape3Ds in a scene. There are couple of ways to reduce the number of Shape3Ds in a scene:
