Hi,
I'm trying load animated files exported from 3ds max 4 in vrml format using
xj3d loader. In many case there are errors parsing the file.
An idea ?
Thanks

Hi,
you can call the System memory methods to determine the memory used by the
VM. If the VM memory drops after the gc your graphics driver software might
be the problem.
If the VM memory stays at the high level it seems that your objects are not
garbage collected at all. Then you have to check
Hi Kyle,
you reminded me of something. Perhaps some other people could comment on this,
too.
The setting i currently use is -Xms32 -Xmx128

I have been doing some research is performance tuning of j3d.

the frame rate would level to the slower.

You can combine Swing components and Canvas3Ds within the same window. Just

Hi,
I have an application where the user is dragging objects around the scene.
When there is no user interaction I lower the frame rate to about 1 frame
per second
to save CPU power (calling View.setMinimumFrameCycleTime().
As soon as the user clicks the mouse I increase the frame rate. But

By making this kind of binding, you defeat the purpose of having Java3D in
the first place. One of the main ideas behind Java3D is that it is portable
across many different platforms, using native libraries on each system.
Using OpenSceneGraph, you limit yourself to PC platforms. If this is

If you were interested in putting controls right on the 3D window, you
should consider an overlay. Theres been a lot of discussion on that issue on

Nope. But if you could send me privately a couple of test files and
the error messages, we should be able to fix it.

Sensors of all kinds. X3D Sensors are not the same as Java3D
