Hi Wigbers, I have sent to you a sample code where you will find a set of 3d objects jumped with the camera viewplataform. The idea for you problem is the same. Where you have the 3d object, all you need is just to put you robot view in it. I hope this help u. §:0).

Hello,
I want to play VRML97 animations in java 3D. Should I use the old VRML97
loader from sun or Xj3D ?
Can somebody send me source code examples for playing back animations,
please?

We recently wrote a loader for the flexporter format to move skin and bone
animation from 3dsmax/char studio. Currently we assign the bone names using
the CSIDS that flexporter produces, but eventually we will need to map the
bones back to standards Bip01 names also. I was planning on asking Pi
Hi,
I'm trying to load a number of models into a switch group and then

Models are taking about 3MB RAM for the geometry and have 8 or 9 JPEG

John,
To be sure that the problem you've encountered is fixed in our
next release. It is best that you send us a test program and the steps
to reproduce it, eventhough we might have fixed a bug that seems to have
the same problem. You never know unless it's tested with your program.
Thanks
Hello all,
I was debating on the pros/cons
to using GeometryByReference. As of now, I just find the object and replace it
with the new one. Is going the GeometryByReference pros outweigh the speed
issues of detaching all the objects all the time?
Thank you for any input.

Are you mipmapping the textures? That would double the memory. Are you
sharing textures for models if they are the same? That would help reduce
texture usage.

are JPEG textures decompressed on loading? 200K of jpeg could be a whole

I am new to Java 3D and 3D graphics. I am trying to load some geometries using

Well it sounds like the default plugin that a user automatically downloads

Ewan,
Sorry, if my questions sound silly. Is there any difference in
those models ( w and w/o texture) ? Is it possible for your apps. to do
the following (or maybe you're already doing that) :
1) Do a multiple load, say 30 times, of a model with texture, and print
the memory usage.
2)
Thank for the samples...
By the way, I am working on an animation framework.
Probably I will introduce some points here in the list, with results of my study
about FlexPorter in a couple of days.
take care

For as much asi remember you can only detach and attach a BG,
if you want to detach TG or any other objects from the scene graph
you need to wrap it in a BG.
