In this talk I will present geometric manipulation techniques for shapes in 3D and 2D that are based on differential representations. Such representations encapsulate important local shape properties and enable a variety of useful modeling operations, which preserve the local details of a shape, and thus its appearance. I will discuss several geometry processing and shape modeling applications based on the differential framework, such as quantization of geometric information, detail-preserving mesh editing, shape interpolation, surface detail transfer and feature-aware image warping. We will see how the geometric deformation mechanisms can be effectively combined with intuitive user interfaces to allow interactive free-form deformation and sketch-based editing of complex shapes.

Refreshments will be served
