Bézier Triangles with G2 Continuity across Boundaries

Bézier Triangles with G2 Continuity across Boundaries

PN (point-normal) triangles are cubic Bézier triangles which meet at their edges to surface a triangular mesh, but this only achieves G0 continuity. We define blending regions that span the edges shared by adjacent pairs of triangular domains and blend the corresponding Bézier triangles using a univ...
