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.
