Unless I misunderstand the problem, one possible approach is to use a CSG
representation for the objects, subdivide the space into boxes, eliminate
boxes where the implicit surface can't be, and use a marching-cubes algorithm
to recover the implicit surface from the remaining boxes.

Hi again,
You should not need to override the paint method if you
use java instead of javaw as the Java application launcher.
The 'extra' code put there is the:
Toolkit.getDefaultToolkit().sync();
and this was a workaround found by Scott Rutledge for
the following bug:

First thing you should do is upgrade the Java3D version, it has come a long
way since then. I'm using Java3D 1.3 and am able to do it successfully on
Windows platform.
You have to set the COLOR_WRITE capability of LineArray and then use the
setColors method.
This feature is BUGGY on Linux version
Hi,
Is it possible to change the colors of LineArray at runtime? I am
initially drawing lines as LineArray in white color. Later, i tried to
change the color to black. However, it is not getting reflected on the
Canvas3D. I am using JRE 1.2.2 / Java3D 1.1.3.
Thanks

Hi,
You best bet may be to use by ref geometry and the geometry update interface (can't
remember the exact interface name).
Basicaly, using this method, you can alter the locations of your coordinates in the
array directly (as long as it is done using
the above mentioned interface). You can the

Yes this is a bug in Text2d.java
The setString(String text) method draws a new image for text, and tries to update the
image in the Texture using setImage(0, newImage). If newImage is not the same size as
the old image that was at level 0, then java.lang.IllegalArgumentException is thrown.

Hi Alessandro,
Thanks for responding. I tried adding those lines and I still
got the exception. Then I tried using your code and I still got the
exception. What am I missing here?
It also doesn't seem like the type of exception I'd get if I didn't
have a capability set.

Another question, Roger...
I noticed you refer to 'javaw' ... would still need to
override paint when using 'java' ?
Basically, do you get similar performace when using java as opposed to
javaw?
I'm going to try your version of the code when I get some time...comparing it to
my code
Also,
is there a difference depending on what java you use...1.3 versus
1.4?

Hi, Roy !
There is no Text2D bug.
you just forget to add the following lines :
text.setCapability( Shape3D.ALLOW_GEOMETRY_READ);
text.setCapability( Shape3D.ALLOW_GEOMETRY_WRITE);
See your code working in the zip file ;)

I've seen a posting back in May about a possible bug in either the
Text2D class or the Texture2D class, but I couldn't find any resolution
on the problem.
Now I've hit the problem too and I'm thinking that it's a bug.
The problem is I get an "illegal image size" exception when I try to

Hi All,
It took us a while to re-produce the same bug in the test environment.
It seems there is a bug in LineArray in Linux version of Java3D 1.3. If we
set the capability bit for "ALLOW_COLOR_WRITE", the geometry gets messed up
with more than 1500 lines or so. If I remove this capability then
Hi,
Do you have, by any chance, some performance results - in frames per
second - of using overlays in 2D instead of 3D ?
In the applications I'm developing, I started using the 2D approach
(postRender, Paint, etc etc) and then I switched to 3D elements, and I
obtained (consistently) better perf
Hi,
No I have experienced the problems you describe. The only
thing that have caused me problems was swing bug when using
javaw. This bug causes drawing problems for components that
are not double buffered, and I guess some of your symptoms
might be from that or similiar bug.
Apart from that it

Hi
Jack,
The
PhysicalWidth & Height are 0.0 because, most probably, you still don't have
an active view attached to your canvas3d at the moment when you invoke the
getters.

Title: Message
Florin,
Thanks, this does work (mostly). Should have remembered the component
needed to be realized first. For some reason, PhysicalWidth and PhysicalHeight
are still zero, but these can be approximated using the constants documented in
the Screen3D Javadocs.

Matthieu,
No, at this time we do not load any animation data nor lights. Our
loader is intended for loading "models" (which we also use extensively
for terrain).

Hi,
I'd like to know if Starfire 3ds file loader can load
animation exported from 3D Studio (in a behavior node ?).
Can it load lights ?
Thanks for your help

First of all, after installing RH 8.0 into my PC, I tried to compile Mesa3D

Hi Ranjan,
A similar application is normally being used in CAM programs using surface

with, and moves over the surface. What is being used sometimes is a
so-called offset surface. Offset being the radius of the cutter. S

It's
not related to java3d but to the awt subsystem. You can't get any valid values
from your canvas3d (or btw any other awt component) before the native peer is
created. You should first create your frame, put inside your canvas3d with the
