[Scilab-users] Intersection of wavy surfaces

[Dang, Christophe]

Hello,

I'm trying to plot two perpendicular wavy surfaces (sine or cosine)
and their intersection,
to illustrate that an edge cumulates the defaults of both surfaces
(the waves represent the grooves from a milling process).

So, for each surface,
I define three mxm matrices X, Y and Z
and plot with surf().

To fit the surface with the other one,
I place some %nan.

It's OK except that :
* if I have too few points, I get some scale effect;
* if I have too many points, it's too dark (too many grid lines);
see the attached PNG (top: 101x101, bottom: 201x201),
and the Scilab script (maybe not too clean...).

Apart from this, It seems I can't export vector graphhics:
the SVG and PDF files have a size of 0,
and it seems to freeze Scilab
(scilab-master-1380896469).

So:

does anyone have any suggestion to improve the rendering?

Does anyone have a guess about the bug of vector graphic export?

Best regards.
