Dear All,
I've just been testing my old Java 3D examples in Java 3D 1.3 and
noticed a strange problem with the diffuse color in a Material
object for a Cylinder.
When the example is run using Java 3D 1.2, the diffuse color
is red (as intended), but in Java 1.3 it displays as white.
The other col
Dear All,
I've been writing a simple client/server application where a thread
in the client monitors a socket -- when data arrives it is converted
into a Branchgroup and added to the scene graph on the client with
addChild().
4 out of 5 times this works fine, but the other time the new
branchgrou
To try either case, please comment out the other part accordingly. You'll
find help information for you to do that in the program. Please try it and
tell me what do you think. Thanks a lot white

Hi,
I have 2 polygons each has 7 points, they share 3 points, so the total
unique points are 11. I tried 2 ways to render the 2 polygons.
1. Manually triangulate the 2 polygons, send the array of triangles to
GeometryInfo class to calculate normals and render the shape. The result

If I'm not mistaken, ConfiguredUniverse is for Java3D 1.3 and we had to
use 1.2.1 but the whitepaper was definitely a

Absolutely. How would we contribute exactly?
If you want the code to be open and modifable by others, you could
always put it into the j3d.org codebase. We've got a

They will not be rendered in their index order. Only OrderedGroup and its

Subject: [JAVA3D] BranchGroup and OrderedGrou
Just a little question, but, if i use a branchgroup instead of orderedgroup,
can i be sure that BranchGroup's children will be rendered in theire index
order ?

Once the first object has collided with the second, it won't pick up any

Unless you mean that after the collision, the first object is not allowed to

Hi Patti,
The problem is that the viewer is too close to the models, and there is
nothing to be seen! It's all just black. The only way to see the 3d models
is to zoom away from them. I think that you should set the correct position
for viewing the models right from the beginning.
Cheers,

hello,
actually i got a problem with color depth. i can only get a color depth of 256 colors for the texture instead of all colors. at the examples of java3d there is the same problem. so i like to ask u how i can get the full color range for textures ?

It's rather straight forward, no specular shading as this would need a
view dependent recalculation of the texture coordinates and as long as no
Vertex shaders are supported in J3D I think it's not worth the
trouble. Alltoug

Probably a basic question, here goes...

suppose i want to draw two spheres at different locations on my scene,
