报告摘要：Reconstructing 3D surfaces from point clouds is a fundamental problem in digital geometry processing and 3D vision. Among the various approaches, implicit function–based methods have become particularly popular for their ability to recover complex topologies and their robustness against noise. Poisson surface reconstruction and its variants remain among the most widely used techniques. Traditionally, these methods assume that input point clouds are equipped with globally consistent orientations, making point orientation a closely related and critical subproblem. Until recently, research in this area largely advanced along two separate directions: one focusing on estimating consistent normal orientations, and the other on reconstructing surfaces from oriented points. In this talk, I will present a series of recent projects that unify these two threads into a single, coherent framework that jointly addresses orientation estimation and surface reconstruction. I will conclude with a discussion of emerging trends and open challenges in this rapidly evolving field.
