[Scilab-users] Compute normals to 3D surface

[Lester Anderson]

Hello all,

I was wondering if it was possible to compute and visualise the normals to
a 3D surface in Scilab? I think Matlab has something called surfnorm;is
there something similar for Scilab?

I have attached the basic code for the Moebius strip, and it would be
useful to showwhat happens to the normals at say z=0, but not sure how one
would go about this. Perhaps this has already been solved.

Cheers
Lester
