Where I said I mean sum of functions? Where I said I mean any sum ?
For the opinion "Converting arbitrary point sets into meshes or surfaces is a
difficult task" I replaied that isosurface can be considered as set of points
where desription of set is a given function. Of course the difficult part is
finding that function for given set which is another task. I just wanted point
out that isosurface can be a tool in mentioned "conversion".
