Hi again,

OK,
some more background:
I actually want to perform a delaunay triangulation on a set of
X-Y-Z-coordinates.
I suppose you mean a triangulation of scattered X-Y-Z but you call
mesh2d with X-Y only ?
I know of CGLAB, but it seems only available to Scilab 6.0.x, while I
am on Scilab 6.1.0
CGLAB is based on a very old version of CGAL and thus is very hard to
maintain as is. There is a lot of work...
So the nearest thing to a delaunay triangulation I found is mesh2d...
Yeah. Suboptimal choice indeed...
Because of the delaunay triangulation, I am not sure if the order of
points may change.
What do you mean ?
About unique:
The result I get is actual of same size as the input matrix...I
therefore do assume that each point is unique in the first place
(which they actually should).
What does repeat are individual x, y, z coordinates, but in different
combinations.
So the actual point is different.
e.g.: x may repeat, but than the y-z-coordinates are different from
point to point
Could you share the data (you can send me a private message) ?
S.
Thanks,
Philipp

Hi Philipp,
Glad to hear that some people use mesh2d. I know we have to
improve the error message by getting the numbers at the Fortran
level... There is also other errors which are not easy to fix
without knowing the number of the problematic point (point too
close to the boundary, for example). Can you file a bug on BZ ?

Dear all,
using the mesh2d - function I get an error: mesh2di: some points
are identical.
How to identify these points and remove the duplicates?
There are roughly 500'000 coordinates....
Thank you,
Philipp
