Hehe, as usual, it's the grid descriptions that confuse people who are not familiar with meshing problems. Not that I feel like blaming you: I have been there. > Do you mean: All permutations between the given x and y array points > are made, and only when they exacly represent a coordinate of the s > array, that value is taken and being drawn? The points should lie on an orthogonal grid: the x position is independant of the y position, and vice versa. Thus only 1D arrays are required to describe the problem. However, 2D arrays can be given to make people's life easier.

It makes it easier for other people to comment. And it's not like this mailing list is high traffic.
