Abstract
Various embodiments of a system and methods for generating a manifold surface of an object from a set of 3D curves which define the shape of the object are described. The set of 3D curves may be directly tessellated in the 3D domain to form a manifold surface with boundary. The tessellation may be a Delaunay tetrahedralization which represents the set of 3D curves. The surface of the tetrahedralization may contain a set of possible manifold surface solutions. A dual complex form of the tetrahedralization may be generated to reduce the number of possible manifold surface solutions. Surface patches may be generated from the dual complex form, dependent on a set of metrics that may further reduce the number of possible manifold surface solutions. Compatible surface patches may be combined to form a set of possible manifold surface solutions which may be displayed to a user.
