# How to draw metaballs?

Some examples are in http://en.wikipedia.org/wiki/Metaballs. Can we draw them in scientific software like matlab, mathematica,...?

It is certainly possible. You've linked to the wikipedia article which gives an explanation of how metaballs are generated. Is there something specific you're having trouble with? –  axblount Oct 5 '12 at 15:21
I know those formulas. But I am not familiar with scientific drawing. Can you give some code examples? –  LittleSweet Oct 5 '12 at 15:26
In Mathematica, I think RegionPlot3D would be well suited for this. The colouring of the balls would then be done with a suitable ColorFunction. –  celtschk Oct 5 '12 at 15:30
I googled RegionPlot3D, it looks cool. Thanks! –  LittleSweet Oct 5 '12 at 15:34
