Abstract

Generating surfaces from spatial curves with topology constraints is a fundamental task in computer graphics. It has numerous graphics applications, such as computer-aided design (CAD), product prototype and biology shape analysis. Though classic and widely-needed, topology-aware surface reconstruction from multiple spatial curves stays a daunting task in computer graphics because of the enormous ambiguity in the geometry and topology of a surface. In this dissertation, we propose three methods tailored for reconstructing surfaces with specific topology properties. The first method obtains a manifold triangulation of multiple, arbitrarily oriented 3D polygons. The surface is guaranteed to be manifold and optimizes a user customizable metric. The second and third method study the reconstruction problem on curves from cross-sections. In particular, we offer topological control during the reconstruction. A family of topologies is explored and scored during this process. The second work focuses on a novel complete framework for reconstructing surfaces with user specified topology and the third work extends the topology exploration of this framework from handling two materials to multiple.
