Uneven meshing can cause the relaxation to fail or give incorrect results, especially when the relaxed geometry changes significantly from the input, causing the triangle quality to degrade even further.<br /> <br /> By continuously updating the connectivity of the mesh, as shown here, to maintain even sized and nearly equilateral triangles, even very large changes to the boundaries become possible, and the surface still minimizes mean curvature. This allows dynamic exploration of sculptural forms.<br /> <br /> Special thanks to Will Pearson for all his work on the Plankton library.
