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

Hi Everyone,
This is off topic for this mailing list but I don't know where else to ask.
I have N tabulated data points { (x_i, y_i, z_i) } that describes a 3D
surface. The surface is pretty "smooth." However, the number of data
points is too large to be stored and manipulated efficiently. To mak
