I'm trying to draw some smooth looking surfaces with gridlines, and I'd like the grid lines to be invisible (or transparent or whatever) when they are obscured by my surface. In my code below, you'll see that I manually added the gridlines, because otherwise they seemed to become piece-wise linear.

How do I hide the lines behind the surface in a "smart way"?

    Welcome to TeX.SE! How about adding mesh and decreasing the samples? Like addplot3[samples=30,surf, domain=-3:3,mesh/ordering=y varies] 0.1*(x^3-y^3); ?

I'd just do

begintikzpicture
beginaxis
 addplot3[samples=30,surf,shader=faceted interp, domain=-3:3,mesh/ordering=y varies] 0.1*(x^3-y^3);
 endaxis

enddocument

Whether or no you use shader=faceted interp is not too essential here. You'd need to use spy glasses to notice a difference.

If you look very closely, you'll note that the tiles on the right have some gradient shading whereas the ones on the left don't.

            One-line joke

            A one-liner is a joke that is delivered in a single line. A good one-liner is said to be pithy - concise and meaningful. [1] Comedians and actors use this comedic method as part of their act, e.g. Jimmy Carr, Tommy Cooper, Rodney Dangerfield, Norm Macdonald, Ken Dodd, Stewart Francis, Zach Galifianakis, Mitch Hedberg, Anthony Jeselnik, Milton Jones, Shappi Khorsandi, Jay London, Mark Linn-Baker, Demetri Martin, Groucho Marx, Dan Mintz, Emo Philips, Tim Vine, Steven Wright and Henny Youngman and Arnold Schwarzenegger. [ citation needed ] Many fictional characters are also known to deliver one-liners, including James Bond, who usually includes pithy and laconic quips after disposing of a villain. [ citation needed ] Examples "A baby seal walks into a club." "A dyslexic man walks into a bra." (Anonymous) "There are three types of people, those who can count and those who can't."
