Spline surface Discretizations GPDE Convergence
2012/8/8
Variational formulations of three fourth order geometric partial di甧rential equations are
derived, and based on which mixed 痭ite element methods are presented for constructing
G1 smooth B-spline sur...
When parametric functions are used to blend 3D surfaces, geometric
continuity of displacements and derivatives until to the surface
boundary must be satisfied. By the traditional blending techniqu...
