MetaBall-Pseudorandom[25]” v4W.ENko - "PS-17. MetaBall-Pseudorandom[25]". The basic "PseudoRandom" is generating 25 vertices to continue the visual story about the "MetaBall Algorithm". The outlines are colored in the list of complementary colors depended on the sub-settings of the "metaball" charge centers. "Pattern Standardization" series is upgraded with more complicated "MetaBall" structure and generating the form such as the "Abstract michro-scheme". The "links-lines" of the "metaball" charge centers are generated with "Delaunay triangulation".
