I think you should use the following codes, and add your created shape
object to the "sbranch" object. Using detach methods can solve it. Any
further questions, please contact me.
BranchGroup sbranch = new BranchGroup();
sbranch.setCapability(BranchGroup.ALLOW_DETACH);
sbranch.setPickable (false
David,
It looks like your method of handling terrain is similar to the tile-based
system described in Game Programming Gems 2. This is the same approach I'm
using. It may not be as sexy as ROAM or VIPM, but it's reputed to be
faster. And I believe it's far more scene-graph friendly. The trick

I attach two files from the java3d package which is developed by NCSA. If
you want to download the whole package and want to run the application, you

Wow, thanks for the excellent description! The sophistication of your
approach is impressive.
As for the people who discount the approach, let me say that I'm not one of
them. While your system is vastly more mature, I just started working on a
similar approach in my spare time (based on the Ge
How do I remove shapes from the scene graph? Would the
best way of making bullets be creating shapes, then
adding them, moving them and removing them when they
are off the screen?

I tried the code in the zip file, but nothing appears,
what's wrong. Bill i got your example at "3D graphics

changes, to show a 3d text with the word "Gaciv", but
it didn't occur.
Thanks for all, Fábio

I just want to weigh in here with an alternate technique. This technique is
optimized for fairly slow movement speeds. Our current implementation can
handle up to 50 meters a second without a problem, but after that it can't
keep up. Not a problem for us, but could be for other people.

has anyone tried using the CapturingCanvas3D class in the j3d repository
code. i tried it as how it suggested to be implemented but nothing came out.

thanks in advance.

Title: RE: [JAVA3D] ROAM and GPU Usage (off-topic)
Justin and others,
You mentioned that sending the triangles every frame to the hardware is not GPU friendly, because they must be clipped and culled every frame. However, for a GPU, isn't this done in hardware anyway? (According to NVIDIA'

Hi all,
is there any way of writing values to the Z-Buffer before rendering the
scene (in the preRender() method)? What I'm trying to do is display a
fixed-perspective 2D-image with depth information (output of the rendering
software) and then display various 3D-objects that can get obscured by pa
I can believe this, although your scene graph must be very big. Here are some
reasons why this is the case. These are not completely specific, but
the general numbers are what is important. In the first case, we are setting an
attribute on a Shape3D node. One thing to note is that Shape3D node

Correct, sorta. At least here on this laptop (ATI Rage M3/833Mhz CPU) it
seems to run reasonably well with the small terrains I'm testing on. Not

Hi Kelvin,
First of all thanks for accepting and filing bug#4632388. Secondly,
I filed a couple of reports in Sun's Bug Database in late December
and since then haven't heard anything from Sun. So I though maybe
it's a good idea to post reports to this mailing list.
Thanks,

I'm under the impression that ROAM is CPU intensive and not very
GPU-friendly.
I've done some reading into both ROAM and VIPM. I haven't yet implemented
either, but I've read a few articles recommending VIPM over ROAM.
Opinions?
