This is a weekly posting of topics covered in the Java 3D FAQ. The answers
to these questions are kept at:
http://tintoy.ncsa.uiuc.edu/~srp/java3d/faq.html
Please consult this list and the web site before asking questions on the
list.
Justin and I can't provide a "one-on-one" answering service for Java 3D
questions. It's best to ask questions on the mailing list, instead
of mailing us directly.
Thanks,

Programming Questions
---------------------
1) Where is the documentation for the utility classes that Sun provides?
2) I have a GeometryArray, and I'd like to get the Coordinates out of it
using the getCoordinates(int index, Point3d coordinates[]) method call.
I've allocated the array, but I'm getting a "Null pointer exception"
and everything else looks right. What's happening?
3) I drew several things on the screen, but when I display the scene, it
looks like the objects in the back are actually in front. How do I stop
that from happening?
4) I have a flat plane in a scene, but I can only see one side of it. What
can I do to see both sides?
5) I can see both sides of the polygon, but the coloring on one side seems to
look flat, even though there is a light shining on it. What's wrong?
6) I get an exception that says Locale doesn't have the capability to
detach a BranchGroup. How do I fix this?
7) I have 3D data that isn't three or four sided. Does Java3D provide
any utilities to triangulate these polygons for me?
8) Does Java3D provide any utilities to generate normals for a set of
faces?
9) I'm trying to use the Triangulator, but I get a null pointer exception
thrown in an object called GeomInfoConverter. Why is this happening?
10) I keep getting an IllegalArgumentException: Index lists must all be
the same length when I use the GeometryInfo object. What am I doing
wrong?
11) I'm trying to use Swing components with Java 3D, and I'm seeing
odd results. What do I have to do to get everything to work correctly?
12) I have a 3D world that has a some spheres and cylinders and everything
seems really slow when I try and move around. I also get out
of memory errors, even with a small number of objects. What could be
happening?
13) I'm trying to share nodes across multiple universes and I'm having
problems. How do I do this?
14) I want to work with the serial device on my system to communicate with
a hardware device so I can use it with Java 3D. Do I have to write some
JNI code to access this?
15) I've seen the 3d texture mapping example, but it doesn't seem to work with
the system I'm using. Why doesn't it work?
