Hi,
I am the process of writing a graduate CS report where
I evaluate Java as a game platform. Among other things
I am going to run some benchmarks with Java3D.
My question here is; does Java3D 1.3 beta 1 has different
performance characteristics that 1.2? Is it faster? I ask
because it is essen
Hi
I'm not sure if someone else has experienced this problem. But
I've got serious performance problems with the ATI R200 with
Java3D OGL compared to say a Geforce2mx400 (though the later one
is far less powerful). Anyone else experienced something similair?
I can only guess it's a driver proble

Hi all,I have a problem with installation Java3D API.
I would work with OpenGL version and I try install the OpenGL sdk version in my Window
NT.
During the installation I find this problem when I must choose
1)Add Java3D to these JVMs
2)Choose a JRE VM
3)Choose an SDK VM
I have choosen the first
It is faster. It is is also more efficient. I don't envy you your mission,
because it is very easy to write slow Java3d code. The problem is that most
of the time if your application performs slowely it is because of poor
coding. It's hard to even just calculate triangles per second, frames pe

Thanks for the info.

Hello all,
Is there a way to access the visibility culling performed by Java3D in
my application?

Changing the PolygonAttributes to CULL_NONE, produces the image of a
sphere defined with points. The affect of texture is totally lost, leave
alone the transparent gif ? Any Ideas as how i could use transparent gif
as a texture.

Very exciting study. I am sure Jeff Kesselman over at JavaGaming would like
to see the results of the study.
I am curious about a few things:
1. How will you compare Java3d's ability to create optimized output streams
to that of the other 2 API's? Java3d sorts output atoms by materials and

Dear Java3D members;
I have a question about the appearance of Shape3D:
1) I created an appearance
//Create a cylinder
PolygonAttributes attr = new PolygonAttributes();
ap = new Appearance();
Material mat = new Material();
mat.setLightingEnable(true);
ap.setMaterial(mat)
Does anyone have an example of using HiResCoord?

Well I made the recent experience that in some cases the performance gain
is more than a magnitude. Especially concerning wakeUps and Behaviors.

I am looking to see if someone has an example using java3d for multipipe

only one pipe would do something. Therefore, I am wondering if

Add my voice to the praise for v.1.3.
I've had a week now to explore setSchedulingInterval(), and I've
been startled by its appetite for all of the procedural kluges
that had infected my models. More and more things can be moved
onto the scene graph where they belong. I can even see daylight

Jacob,
You should use the latest Java3d1.3beta1 for your benchmarking. It's
performance superseded all earlier versions of Java3d in our inhouse
benchmarking run. By the way, perf_guide.txt contains important information
for writing efficient Java3D program.

Murat,
This seems like a Java3d's bug. Are you using Java3d1.3beta1 ?
Can you send us a small test program that can reproduce your finding ?

Java 3D only does view frustum culling and its result isn't accessible
to application.

Hi Micahel,
There is a typo in the file
_think/net/monoid/j3d/animation/models/md3/MD3Model
Change
geomArray.setColorRefBuffer(new J3DBuffer(coordBuffer));
to
geomArray.setCoordRefBuffer(new J3DBuffer(coordBuffer));
should work fine.

No. Java3d1.2.1_03 is Java3d1.2.1 with bug fixes. Java3d1.3beta1

Thanks for your super fast reply. Looks like using smart double buffered
overlays in 3d will continue to have optimal performance and portability.
We will stick with our overlay system.

Hi,
Maybe you have to tell the box to generate normals - you are using a material
and lighting to colour the box. To do this use the following constructor to
create the box:
Box box1 = new Box(40.0f, 50.0f, 60.0f, Box.GENERATE_NORMALS, ap)
Hope this helps,
