Hello Kelvin and Lee,
I'm using the latest OpenGL version (1.2) of Java3d, although this the
problem has been there already in version 1.1.3.
The reason why I'd like to get rid of those lines is that my geometry
represents buildings and there each line should have a meaning.

I need help. I'm making a 3D

parameters are already set up and fixed at the main class. How can I
make it so that during runtime I can change the parameters and directly changes

I am trying to create a GeometryArray with multiple texture maps. I am
not clear however how to specify multiple sets of UV coordinates. Are
they just all put in one big array? If so, how do we specify which vert
goes with which?
I'm confused. Any help would be appreciated.
Thanks

Hi
I waited that Java3D calculated for the user the vector of the normals.
Why is there the constant GeometryArray.NORMALS. When I do use this
constant.
For exemple :

GeometryArray.COLOR_3 | GeometryArray.NORMALS);

errr.um. NFI.
Anybody else seen this/care to comment? I've only got an NT and Linux
box at home so I can't test the DX install routines.

The only outstanding bug we've on picking util. in 1.2FCS is :

It will be fixed in the next Java 3D release.

Hi Pasi,
Are you using DirectX version v1.1.3 of Java3D ?
Using OpenGL version of Java 3D should work fine.
Thanks.

There is a known bug in the Pick utils code, where picking any Strip geometry
type can fail or be incorrect.

I had similar problems, and my conclusion was that it performs a
"pickRandomly" type of function. So I moved back to the old PickObject API,
which at least seems to work. Has there been a bug report about this? I
didn't report it because I saw so many people in this group complaining

Well, I just move to using this driver as well and all is well...
polygon attributes no longer change the frame rate. Hmph, it was just the

Well, thanks for all your help.

Lee,
I'm running in 16bit with the 5382b08 driver from ATI's site.
When I moved to this driver, my performance increased noticably. This was the most

and fastest driver from ATI that I've found for my video card. It's claimed to be a
'beta' driver,

It sounds like you are building a box using TriangleStrips of some sort.
Each side of the box is actually made of 2 triangles, thus the diagonal line
