Abstract :
A C^1 convex surface data interpolation scheme is presented to preserve the shape of scattered data arranged over a triangular grid. Bernstein–Bezier quartic function is used for interpolation.Lower bound of the boundary and inner Bezier ordinates is determined to guarantee convexity of surface. The developed scheme is flexible and involves more relaxed constraints.
