jim c Posted September 30, 2011 Share Posted September 30, 2011 I've seen these mentioned in posts here, and in other tutorials. But I don't understand - what is it about metaballs that make them so special to use for particle (and DOP's too I think) forces? Quote Link to comment Share on other sites More sharing options...

But I don't understand - what is it about metaballs that make them so special to use for particle (and DOP's too I think) forces? Metaballs are convenient way to define a force field, or any field. Having a bunch of points and some well known function (kernel), you can compute effectively some value at any position in space. So you interpolate a values which are carried by points to a three dimensional field. Secondly, metaballs have almost analytically defined iso-surface, which makes them easier for meshing.
