,Hermite Bicubic Surface
•The parametric bicubic surface patch connects four corner data
points and utilizes a bicubic equation.
•Therefore, 16 vectors or 16×3=48 scalars are required to determine
the unknown coefficients in the equation. How?
•Corner points=4, corner tangent vectors=4×2=8, corner twist
vectors=4.
•The parametric equation of Hermite bicubic surface patch is
