VRML is composed of a number of versions. VRML97 is the current one (aka

We test constantly on Win98 and were seeing some problems that sound

Thanks for the analysis. The reason why the multi-texturing performance
is much better when you put everything into one geometry array is
because currently we are using vertex array for multi-textured geometry array.

I have heard that Win2K does handle threads better than Win98/ME.
But since the whole machine is wedged, I don't think it is a Java

Hi Lee,
There are several things you can try, I assume you

If Java3D Fly is using the loader interface(ie time-zero, no animations)

sooner as things are going well in cleaning up the code. Is there an

This feels a lot like a deadlock. Moving from OS to OS can change
thread timing and scheduling behavior. Is there any way to get a
thread dump, or are you completely wedged?

Kelvin,
The two ATI cards are XPERT 2000 (32mb) and an ALL-IN-WONDER (8mb).
The Nvidia is a CL 3D Blaster RivaTNT2 32MB.
I don't actually think this info is relevant because it freezes up with

HI David,
Thanks for the feedback and suggestions
The intent was for the SweptVolumes to support a number of rays being
cast in each direction, thats why the rays are specified as an array
of Vectors. However the VPDefaultCollision class does not support
multiple rays in the current implemen

Given the TransformGroup from the callback, couldn't you simply do one of

If you do it using the method I use, you need to look at the callback
methods of the picking behaviors. But first, you say when someone picks
object A, you want to change the color of object Qa. So is there a direct
correspondence from object A to Qa and from B to Qb and from C to Qc, and

Hi there,
I have a lot of 3D object, so object A, B, C, etc; e.g. - I need to implement a

Perhaps it would work with WakeupBehavior, but I can't find some way to link
the WakeupBehavior with the pick method.
Some hints ? ...
