Computing displacement distances. Two similar but nonidentical polyhedral meshes are shown as orange and blue line segments ending in circles. Line segments represent individual triangles, and circles represent triangle corners. At every point on both meshes, the displacement distance is the minimum distance to the other mesh, as shown by thin lines with arrowheads at both ends (a, b, c)
