Hi,
I am working on a 3D reconstruction programme with Mma, which gives a 3D=
body based on digitized cross section of animal and plants. This might=
sound a bit odd but is a standard problem in Biology.
Well, the cross sections are usually non convex surfaces which need to be=
triangulated for further measurements etc. I have used the NonConvexTriangu=
late function supplifed in a package with Tom Wickham-Jones: Mathematica=
Graphics excellent book. However, depending on the number of points the=
function fails.
I have send Tom a test file and he had the same problems, so it is not a=
hardware problem whatsoever.
So, my question: does any body know an alternative triangulation algorithm=
or function which I could try?
Or does anybody know a 3D reconstruction programme for Mma?
Thanks alot
