Data Manipulation 2. All part of the animation The basic idea is you draw a gaussian falloff sprite for each blob into a render target with additive blending, such that you get a density field from the sum of the falloffs. Metaballs is a Java library and GUI for creating images using a collection of 2D metaballs (soft object) algorithms. Although an isosurface generally refers to 3D space, it will be seen that it is very easily adapted to 2 dimensions. Metaballs is an old school computer graphics algorithm where you define shapes via an implicit functions and use a technique like marching cubes to trace the edges of those functions on some sort of grid.
