If I say "implicit surface" you may think of metaballs and marching cube, I'll show you there is more to it!

Transforming implicit surface (distance field) and their gradient

This is a simple demonstrator of the HRBF technique presented and explained here. You can visualize and edit the implicit surface generated with HRBF.

Convert implicit surface defined with global support to compact support

Recipe for implicit surface reconstruction with HRBF
