Quadrangle Surface Tiling Through Contouring, T-junctions. Our main contribution is an extension of the discrete Laplace operator which encompasses several types of line singularities. The resulting two discrete differential 1-forms are either regular, opposite or switched along the singularity graph edges. We show that this modification guara

A Developable Surface of Uniformly Negative Internal Angle Deficit,planar polyhedral net. It is shown that simply-connected surfaces of negative interior curvature cannot be developed. An example is then given of a surface of negative interior curvature with two boundary loops, isomorphic to a cylinder, which is developable.
