Hi Andy,
Actually thats a huge task and the
current project does not have that in scope.
Do you know any good NURBS facetter
available which supports TRIMMED NURBS faceting. I am using Parasolid Library
for that purpose right now, but its as heavy as 14MB !
Thanks a lot for your
reply.
Hi Daniel,
I saw the Graphics Gems online sample
code. But unfortunately its too trivial to be used in a product that we are
developing and moreover I need TRIMMED NURBS surfaces, and that makes things
more complicated. I may try to find out a readymade NURBS facetter instead.
Anyways,
Hi,
I try to use J3D(1.2) and a HMD (V6 from Virtual Research).
Have someone already try to do it?
That would be great !!
Any examples are welcome :-)
Thanks

Hi,
I'm trying to off-screen render into a BufferedImage, which is passed to
Canvas3D's off-screen buffer (ImageComponent2D) by reference.
For some reason I have to make a call to
ImageComponent2D.getImage() (I don't need the return value) after rendering
is completed to get anything
Anirban,
I agree that there
would substantial work involved in writing a comprehensive NURBS library, but a
limited library with NURBS curve/surface creation and simple editing could be
achieved fairly rapidly. (Correct me if Im wrong, but the OGL does not support
advanced NURBS
Dear Dr. Alun Moon:
Is it possible to share with me the details of the
papers for NURBS facetting. I am working on a J3D
class loader and would soon be working on faceting.
Thank you.

The doc for PickResult says "If the Shape3D being picked has multiple
geometry arrays, the arrays are stored in the PickResult and referred to by
a geometry index. " It sounds like there's some index that points to which
geometry of the Shape3D was picked. How do I get this index?

Hi,
Referring to my last posting (empty subject field, sorry):
I read the mail about type/format combinations which shouldn't cause
excess copying/conversions (for textures), and tried changing type/format
in my off-screen rendering code to:
b = BufferedImage(256, 256,
Does anyone have any comparison information between vtk and java3d?
Peformance, etc.

Whoo-hoo! When I looked into this a year ago, Shape3D's couldn't have multiple
geometry arrays. This looks promising.

There are still some restrictions, Andrew. With multiple geometries, they
must all be of the same sub class. For instance you can't have a PointArray
and an IndexedGeometryArray on the same Shape3D. You'll see when you read
the API.

I am trying to limit the playing of a background sound to a geometry
area, which is why of course it has scheduling bounds. In the attached
program, I've placed the background sound's BoundingSphere out in
never-never land, but it still plays. Can anyone tell me what I am
doing wrong?
In the com.sun.j3d.loaders, look at the Scene,SceneBase,Loader,and
LoaderBase objects. The describe how loaders should work.
There are other example loaders as well on the loader archive page.

Will,
If you have an sgi you can use ivcat
ivcat binaryfile.iv asciifile.iv
to get an ascii version. This works for
Inventor V2.1 which is a superset of VRML 1.0;
BUT the java loaders probably exist only for VRML 2.0
(correct me if I'm wrong) and will not work for VRML 1.0
since they use

WritableRaster tile = tmpImage.getWritableTile(0, 0);

I agree
why not try Sun's Forte4j ide (ex netbeans)?
It's free, has great support and works for me and for J3D
Cheers, Dave
