Abstract: Two kinds of H-Coons patches with C1-continuity are constructed by two classes of H-Hermite polynomial functions on triangles. Triangular H-Coons patches present extensions of the Side-Side method and Side-Vertex method. These shapes depend on shape parameter
and the limiting case for  0are the triangular Coons patches. Changing the value of , the interior shape of the patches can be adjusted, but it don’t influence the boundary shape of the patches. The examples show that this method for constructing surface is effective.
