In particular, we propose an approach, called Pressing, for smoothing isosurfaces extracted from binary volumes while recovering their large planar regions (flats). Pressing yields a surface that is guaranteed to contain the samples of the volume classified as interior and exclude those classified as exterior. It uses global optimization to identify flats and constrained bilaplacian smoothing to eliminate sharp features and high-frequencies from the rest of the isosurface. It recovers sharp edges between flat regions and between flat and smooth regions. Hence, the resulting isosurface is usually a very accurate approximation of the original solid. Furthermore, the segmentation of the isosurface into flat and curved faces and the sharp/smooth labelling of their edges may be valuable for shape recognition, simplification, compression, and various reverse engineering and manufacturing applications.

We describe a prototype meeting space named inSpace that explores how design grounded in these themes can create a user-driven, information-rich environment supporting a variety of meeting types. Our current space includes a table with integrated sensing and ambient feedback, a shared wall display that supports multiple concurrent users, and a collection of storage and infrastructure services for communication, and that also can automatically capture traces of how artifacts are used in the space.
