Thank you Ben! I will give it a try.

I don't think this is currently possible.

To implement this, I think the `for-2d-sample` loop here needs to change:
https://github.com/racket/plot/blob/master/plot-lib/plot/private/plot3d/surface.rkt#L28

(I guess there should be 2 loops, one to draw the surface and one to
draw the lines)

[racket-users] Plot - Choosing the number of mesh lines independently from the number of samples

[Marduk Bolaños]

Dear all,

Recently, I made a 3D plot with surface3d, but had to increase the
number of samples from the default value in order to obtain a
smooth surface. Unfortunately, this change also increased the
number of mesh lines, which resulted in a very dark surface. The
appearance improved by painting the lines with a lighter color,
but what I would really like to do is to choose the number of
mesh lines that are drawn on the high-sample smooth surface.

Is it currently possible? And if not, what would you suggest in
order to implement it?

Thanks in advance.

Best,
Marduk
