Dear all, Dear Benjamin, Dear Sappy85,
probably I miss the meaning of structured and not-structured grid. In my
grid I have only rectangular element, but they are not regular.
Here an example. In what follows you can see the x and y vector of the
point of one rectangle:
X=0.1000 0.5950 0.5659 0.0951
Y=0.0 0.0 0.1839 0.0309
I would like to do as the Ben's example (
http://matplotlib.org/examples/mplot3d/trisurf3d_demo.html), but with non
regular rectangles.
Moreover, in my my case each point has a different value.
Am I asking to much?
Thanks
Diego
