Many problems in pure and applied mathematics boil down to determining the shape of a surface in space or constructing surfaces with prescribed geometric properties. These problems range from classical problems in geometry, elasticity, and capillarity to problems in computer vision, medical imaging, and graphics. There has been a sustained effort to understand these questions, but many problems remain open or only partially solved. These include determining the shape of a surface from its metric and mean curvature (Bonnet's problem), determining an immersion from the projectivised Gauss map (Christoffel's problem) and its applications to the computer vision problem on recovering shape from shading, the construction of surfaces with prescribed curvature properties, constructing extremal surfaces and interfaces, and representing surface deformations.
