ARC Docking

This plugin provides surfaces representing the interaction between two groups of atoms. Colors can be added to represent interaction forces between these groups of atoms.

The method works as follow:

  • a 3D Delaunay Triangulation with atoms as vertices is constructed,
  • the surface is extracted using a Marching Tetrahedra algorithm,
  • geometry and colors of the surface are given by the nearest atoms.
