Algorithms for generating B-nets and graphically displaying spline surfaces on three- and four-directional meshes

This paper is concerned with the description of an algorithm for generating the B-nets of box splines and an algorithm based on subdivision of these B-nets for graphically displaying spline surfaces on a three- or four-directional mesh. The combination of these two algorithms is shown to compare favorably over the other existing algorithms for this purpose.
