Just exactly what does the intersect() method do?
To me it seems to do no more than just a pick. That is, it tells you if
the geometry and the pick shape intersect. However, it does not specify
what that intersection condition actually is.
To me, the intersection code seems to do just the usual

In the Leyland Needham's Dictionary (0.99 alpha), it clearly says that
low-level is working directly with the hardware in machine code with switchs
on a box :). And hi-level is *before I think* "I would like to see a

Desiree,
You might want to clarify if you are using Java 3D OpenGL or DirectX.
Also did you just swap the video card or did you re-install the video
drivers? Also it's not clear from your e-mail if the problem is worse
or better than before... sounds like it wasn't perfect originally.
All that
Justin, excellent clarification. You are completely correct it depends
on if you look at it from the point of view of a "user" vs a
"programmer" (but then again some people that make spreadsheets think
they are "programming").
And you are correct, in that I too believe many coming to look at Jav

Hi Boris,
For any NodeComponents (or SharedGroups) that are used in multiple places
in the scenegraph the j3f file only stores a single copy of the object. The
API will even handle sharing these object in multiple graphs and loading
the graphs in any order.
The file size issue is under investiga

OK, so if we don't implement the serialisation interfaces then we should
not have to worry about it writing data out that it shouldn't. The

Hi Justin,
If the Node.useData object is serializable then it will be serialized to the
output file using standard java.io.Serialization. If you want some of
your VRML loader data to be stored, but not all of it you should either
make some of the data fields transient or write your own readObject
Terminology... sigh... I'd have to agree more with Lee, Java 3D is a
"high level" rendering API. Although the term "mid level" would be more
appropriate. In Java 3D you can't really get into the really nitty
gritty details and thus it can't be considered "low level".

I m'interested in multiple view behaviour and I have tested it for different panel
layouts. I have a question:
How can I view the object from a different side in every view ? Do I have to set a TG

Thanks in advanced !!

Hi all !!
I'm currently working with 3ds models using the Starfire 3ds loader. I know that it
builds the model scenegraph creating a BranchGroup node (and corresponding
TransformGroup and the rest of children nodes) for every object contained in the model.
I'm interested of implementing an 'ent

I wouldn't really consider Java3D a "low-level" rendering API since you
don't really have access to OpenGL calls. A low-level api would let you
do have access to the accumulation, stencil, frame and other buffers.
For example, Java3D can't do motion blurring... at least not usin
