Hi,
I have installed J3D on INDY (irix 6.5.1) and it seems to work fine. I
say "seems" because I developed my app on a PC, and as INDY is a 256
colors station, I didn't see much of my app.
Anyway no Exception appeared, so I guess it works fine. May be I could try
some examples from the J3D distri
Hi,
I could send to those who are insterested in my download of J3D for SGI wich I
successfully installed.
David.

Hello Adam,
if i understand your mail correctly, you're looking for a way to do Java3D
on Linux hardware accelerated using a nvidia TNT. Some month ago i wrote a
mail to the Java3d Mailing List concerning this topic, but nobody seemed to
be interested, i got no response.
But i can tell you some i

Sorry, can't help. All he sent was an email that said he'd got it
working. He was going to be away until Thurs (US time?) and would write

Hi there,
i've got wavefront .obj file loaded into a scene. there are some shapes
where the front and the back must be visible. to solve this problem i want
to disable backface culling. how can i do this?

Dear Java3D developers,
For the ones that can't wait for stereo to work :-)
I have made a patch for Java3D so that stereo mode works for the
SGI/IRIX version of j3d (version 1.1.1 of the Java 3DTM API Edition).
The patch is dynamic in the sense that the OpenGL call 'glDrawBuffer' is
'overloaded'
I'm doing this using the IndexedQuadArray (and the IndexedTriangleArray) and
the per-vertex coloring is working just fine. However, setting up the
Material really doesn't figure into it - using the SetColors method (or
equivalent) once the appropriate vertex format is set (COLOR_3 or COLOR_4)

If you've set per-vertex colors, have a Material attached, and
lighting is enabled...
To add to what Daniel Selman wrote:
I think the 2D way is a way cool approach to the problem.
Another solution might be to create your own sphere code
There are lots of places to pick up how to generate your own sphere with
triangles
and such.
Then, what you could do is map triangles to what coun

I'm having trouble fetching an image from a jar file using the web3d vrml loaders.
I'm using Windows 95, Jdk1.2.2 and the non beta
J3D.
I'm able to fetch a .wrl file without trouble, but if the .wrl file references a
texture then I get an error message:

Hi Ed,
A Shape3D is a Node (look at the hierarchy). Thus, assuming that your
"getSceneGroup()" method
returns a Group or BranchGroup (we'll call "myGroup") you can iterate through it's
children via:
myGroup.numChildren() and myGroup.getChild(int) or myGroup.getAllChildren(). Then on

Look at the Geometr
Most of the Java3D example programs allow rotation of the scene by
adding a MouseRotate which manipulates a top-level TransformGroup
on the content side of the scenegraph
I need to manipulate the View Platform's parent Transform
(on the view side of the scenegraph) and achieve the same result.

Anslelm,
Sounds like the file references texture images via ftp, check
the url of the textures in the file.

This works OK f
Fixed it! and maybe even found a bug!
In com\sun\j3d\loaders\vrml97\impl\ImageTexture.java near line 127 there is a
statement as follows:
urlObj = loader.stringToURL(url.strings[i]);
This rolls through the alternates for a textures file path.
I added a new line after it which overrides
I would have to look back at what i wrote, but what the tutorial
should say is that you can use the MouseBehavior.INVERT_INPUTS
and move the view around, but it is not the best solution.
I hope the tutorial is not misleading.

The NormalGenerator utility works only on GeometryInfo objects.
Other utilities are the triangulator and stripifier. After the
utilities operate on the GeometryInfo object, the resulting
geometry can be used in a Shape3D object.
All of this is covered in Section 3.3 of the tutorial, including

Just a final followup on our experience loading textures in vrml files inside of
jars... not certain if this applys to other people
yet.
In com\sun\j3d\loaders\vrml97\imp\Loader.java on line 226 the code appends a "//" to
the url path. For some reason now with the
"jar:" prefix having 2 slash
