摘要：

This paper concentrates on shape preservation of 3D positive data. A piecewise rational bi-cubic trigonometric function with six parameters has been built to preserve positive shape of 3D positive data. Four of the parameters are constrained to generate the positivity preserving surface through positive data, whereas, the remaining two parameters serve as free parameters for shape litheness of positive surface.
