Hmm... most of the things I know about are proprietary - but you might check
out the following web pages:
http://graphics.cs.uiuc.edu/~garland/
http://www.cs.utexas.edu/users/amenta/
Both have links to papers and/or free software that might do what you need.
The second link might be your best bet - Dr. Nina Amenta's home page. She
has a 'Directory of Computational Geometry Software' that has a lot of good
stuff on it. Whether any of it is in Java remains to be seen.
Hope this helps,
Burns Boaz

Subject: Re: [JAVA3D] Surface Regression?
What I'm looking for here is a surface regression class, probably something
that accepts a Point3d[] object as an argument, and returns a QuadArray or
TriangleArray.
In searching the web, I found a dead link for "public class Bspline3d
extends QuadMesh3d{...." (the author of which I've tried to copy in this
e-mail.) however I wasn't able to find any other references to that class.
If anyone has some links to good plain-English tutorials on the subject
walking through the math, that would be a great help as well. Any info on
generating NURBS would be appreciated as well.
Thanks
Don

Subject: [JAVA3D] Surface Regression?
I'm wondering if anyone has developed applets/applications for generating
and/or smoothing height fields from an array.
Actually the height field part shouldn't be a problem for me if I have to
make my own class, but developing classes to smooth a surface will be a lot
tougher. I'm looking for a polynomial regression type function, possibly
with methods to tessellate the mesh into a finer grid after the regression.
If anyone has done something like this and is willing to share your source
code, it will save me a lot of time on an upcoming project.
