摘要

Non-Uniform Rational B-Spline (NURBS) has actively been used in various field such as modeling, rendering, production of animation and engineering analysis program, etc., because NURBS has many advantages. It can exactly describe curved surface like conics, sphere and even human body. Also, it is effective at computational calculation because storage to calculate NURBS is far less compared to the other method. Therefore, we use NURBS curve to represent interface from computational data and experiment data. By exactly describing free surface, we can obtain several physical properties for calculating coating condition and compare these results with experimental results. It leads to calculate more accurate coating condition. In this study, we make smooth curve to represent interface using NURBS curve with optimization. And we calculate curvature and contact angle with these results.
