Abstract: | Computer graphics and computer-aided design communities prefer piecewise spline patches to represent surfaces. But keeping
the smoothness between the adjacent patches is a challenging task. In this paper, we present a method for stitching several
surface patches, which is a key step in complicated surface modeling, with polynomial splines over hierarchical T-meshes (PHT-spline
for short). The method is simple and can be easily applied to complex surface modeling. With the method, spline surfaces can
be constructed efficiently and adaptively to fit genus-zero meshes after their spherical parameterization is obtained, where
only small sized linear systems of equations are involved. |
