Abstract
Many problems in applied geometry amount to the solution of a typically nonlinear partial differential equation. We will discuss why it may not be a good idea to discretize the equation, but to take the viewpoint of discrete differential geometry and discretize the theory. A geometric discretization embedded into an optimization framework provides direct access to the geometric structures to be designed and allows one to easily include additional constraints related to intuitive interactive modeling, formfinding and fabrication. We will illustrate this approach at hand of recent work on developable surfaces, gridshells and deployable structures.
