Abstract
Method and system for determining a scalar field on a subdivision surface. The method includes providing a surface mesh including an edge. The edge connects a plurality of vertices, and is adjacent to a plurality of faces. The plurality of vertices correspond to a plurality of values for a scalar field. Additionally, the method includes processing information associated with the surface mesh, and determining a geometric location for an edge point on a subdivision surface. The edge point corresponds to the edge. Moreover, the method includes determining whether the edge is a face-varying boundary, processing information associated with whether the edge is a face-varying boundary, and determining a first value for the scalar field corresponding to the edge point based on at least information associated with whether the edge is a face-varying boundary.
