yes, it can. The way I've seen is to triangulate the surface, then do
"decimation" -- remove the triangles that don't add "much" to the detail
of the surface. I don't know of a way to do something similar keeping
the Cartesian grid -- but you may not need to.
Google "python triangle decimation" and VTK comes out on top, but there
are some other things there that might be of interest too.
