Augmentation of 3D models

Today the generation of raw 3D models has become quite easy. Typical sources for geometric data are: 3D scanning, CAD system output, reconstructions from images and video and so on. However, while these models usually have a sufficient quality at the first glance, the removal of inconsistencies and other optimizations are still necessary to make these raw models any useful for downstream applications beyond mere display. Besides this basic mesh repair, one would also like to convert unstructured polygonal models into meshes where individual faces are of high quality in terms of aspect ratio and the degrees of freedom (i.e. vertices) are aligned to major geometric features. These are the global and the local aspects of remeshing techniques respectively. In my talk I will present a number of mesh repair and mesh optimization techniques which are numerically robust and sufficiently efficient to process large dataset of realistic input quality.
