Summary

Description
English: Left column: lines of curvature make a quadrangulation of the domain. For Schwarz P surface, the lines are orthogonal to OA and OC, and meet the AB arc at π/4. For Saddle tower, the lines are orthogonal to O E and E F, and meet OF at π/4. Right column: lines of curvature make a quadrangulation of the surface in R3.
