if you update data in a live geometry there is a huge overhead. you can
avoid some of it by updating all colors in your shape at once (with
setColors() instead of setColor(), note the plural).
also the output you attached sounds like you are still using the 1.2 runtime
with its incredibly slow garbage collector. you should switch to 1.3rc1, it
will boost performance. it is available from developer.java.sun.com.

Subject: [JAVA3D] Bug in setColor in Beta1
Hi,
I have a function which updates colors of a Shape3D (Geometry is a
LineArray) in a Canvas3D.preRender()-function. This worked fine and fast
before I updated to Beta1.
Now, the setColor()-function is making everything very slow ( I checked this
by deleting the calls). I only get a frame every 1-2 seconds! Also, I get
very huge garbage collector calls (see below), which I do not get without
calling setColor().
Is this a bug, or a problem with calling Canvas3D with GraphicsConfiguration
= null ?
Thanks for any comments, Marco.
