Brief Abstract: Surface models are ubiquitous within computer graphics and geometric processing with multiple existing representational forms.  Over the past decade, as digital scanner technologies become more affordable and accurate, there has been an increase in interest concerning point-based models.  The simplicity of these models is advantageous for multiple applications; however, lacking connectivity limits their application to many geometric algorithms.  In contrast, quadrilateral meshes have a constrained connectivity and are useful in many applications from CAD modeling to engineering-based simulations.

In this talk I address challenges of surface modeling and reconstruction.  Specifically, I discuss feature extraction from point-based models and their faithful reconstruction with more useful representations.  Additionally, I will introduce a novel quadrilateral mesh simplification, addressing its impact to quadrilateral-only improvement and meshing.
