    • setEquilateralFacesLR

      public static void setEquilateralFacesLR​(Mesh3D mesh, double timeStep, double decay, int nodeStep, double limit, boolean holdbounds)
      Uses an energy model to obtain a representation of with triangular faces having maximal equilaterality. Nodes are treated as charged particles; thus the most uniform distribution within the mesh boundary is the one with the lowest energy. See ...(website?). This method uses a local relaxation algorithm.
      Parameters:
      mesh - Mesh3D to be operated on
      timeStep - determines the magnitude the force vector in this physical model
      nodeStep - number of neighbours to traverse
