8.1.30. planar quads
This powerful exercise allows you to plastically modify a given mesh, and then smoothen and convert it into a mesh made from fully planar quad.
1.Flattens each of the quads in a mesh.
2.Equalises the diagonal length of each of the quads.
3.Plastic anchor to prevent drift.
4.ClampLength keeps the distance between 2 points between given bounds but applies no force when the distance is within these limits.
5.Uniform Laplacian smoothing rounds any sharp features of a mesh.
This exercise is using Grasshopper version 1.0.0007
