Multi-nets
Alexander I. Bobenko, Helmut Pottmann, Thilo RörigDescription
Shown are the common underlying discrete structures for various smooth and discrete nets.
The main idea is to impose the characteristic properties of the nets not only on elementary quadrilaterals but also on larger parameter rectangles.
