Abstract :
A positive rational cubic function [8] has been extended to positive rational bi-cubic partially blended function to visualize the shape of 3D positive data. To preserve the shape of positive data, simple data dependent constraints are derived on the free parameters in the description of rational bi-cubic partially blended functions. The developed scheme is local and C1.
