Helmut Pottmann and his colleagues form the Geometric Modeling and Industrial Geometry resarch unit at TU Vienna describe the concept of the PQ strip in this paper. The strip consists of planar quad faces. Fig. (c) by H. Pottmann et al.
By lofting the edges, a developable surface is generated. Developable surfaces can be flattened or unrolled without distortion.
