Hello
Search CyberVRML97 for Java on internet. It is freely available. I hope it
will help, though, you won't find a javadoc style documentation, but you can
generate it using javadoc. It won't be much descriptive but there would be
enough material to let you understand how to use it.

Hi Justin:
OK ! I see your strategy for incorporating SVG content into Java3D.
Looks neat. In fact, even a non-scalable image to start with would
be very useful. Mip-mapping and animation would be a great bonus.

I doubt _any_ 3D graphics API is capable of producing that. The simple

Hi Justin,
Nearly a year back I had posted a fairly long note about getting
publication quality Text2Ds in Java3D. If SVG is an avenue for
achieving this, then I am very interested.
A few (newbie) questions though !
What do you mean by an SVG texture ? Does it involve parsing

SVG is an XML-based 2D vector graphics language/file format. Think Flash
and you have a pretty good idea. The spec is managed by the W3C.

Probably not. If you are using Maya to dump models, you would need to

This sounds really interesting. If you can do this I will
have to edit my conclusions about Java3D to the better.

Once I finish my analysis, I will report to the whole list. We should see
the performance a lot closer to GL4Java when I finish.

I hope one of the SUN engineers will take up the challenge and run the

compilation bug in 1.3B1.

Hi,
according to the documentation of ObjectFile the .mtl files will be

you could use Loader.setBasePath(), again according to the

The .mtl file must reside in the same directory as the .obj file. You
should also use the call setBasePath().
I don't think the Lw3dLoader works with the current version of Lightwave.
It works fine with the examples included, but not with the models I've made.
