Relaxation + Remeshing with Plankton and Kangaroo

Relaxation + Remeshing with Plankton and Kangaroo from Daniel Piker on Vimeo.

When relaxing meshes to produce minimal surfaces, generating a high quality initial mesh can be problematic and tedious. 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.

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.

Special thanks to Will Pearson for all his work on the Plankton library.

Comment by Ángel Linares on April 27, 2014 at 12:37pm: Mmmm...every developer should use a mid-range laptop to test his code. Users will be happier :)

Comment by martyn hogg on April 27, 2014 at 12:01pm: that's amazing... do you need to be running on a super computer to get real time updates like that?
