Hallo,
is there any possibilty, how to create 3D-vector of TIN (triangulated
irregular network) of the output from v.delauny? I have 3D points and v.delauny
makes only 2D-polygons from it..
I wrote some script which solves this, but before I post it, I would like to
know, that I did not something useless.
Thank you a lot
Jachym

This requires changes in v.delauny. Somehow the z coordinate must
be maintained (currently set to 0).

For those (like me) who want to easily generate 3D points,
I have extended r.random to optionally use the extracted
attribute value (m) as z coordinate:
Instead of
x y m
it now optionally writes
x y z m
with z=m.
