SYSTEM AND METHOD FOR DEFINING T-SPLINE AND T-NURCC SURFACES USING LOCAL REFINEMENTS

摘要

A system and method is provided for defining a bi-cubic spline surface in a computing environment. One operation in the method is creating a control mesh with a substantially rectangular structure (150). A further operation is inferring from the control mesh the tensor product B-spline basis functions for each control point (152). The surface can then be computed based on the basis functions and the control mesh (154).
