"description": "The Metaball SOP creates metaballs and meta-superquadric surfaces. Metaballs can be thought of as spherical force fields whose surface is an implicit function defined at any point where the density of the force field equals a certain threshold. Because the density of the force field can be increased by the proximity of other metaball force fields, metaballs have the unique property that they change their shape to adapt and fuse with surrounding metaballs. This makes them very effective for modeling organic surfaces. For example, below we have a metaball. The surface of the metaball exists whenever the density of the metaball's field reaches a certain threshold:",
