ABSTRACT
Highlight lines are well known surface smoothness evaluation tools. This paper explains a method with which the designer is enabled to smooth surfaces, by adjusting its highlight lines. The adjustment of highlight lines is performed by replacing the defective parts with replacement curves of designer's will. The modified control points of the surface, which produces the desired replacement curves, are determined using a genetic algorithm. The method's advantages are represented by using better replacement curves and an algorithm which, no matter how complex the replacement curve is, can find modified control points in the absence of algebraic relations.

Efficient NURBS surface fitting via GA with SBX for free-form representation
An accurate technique to perform NURBS surface fitting via genetic algorithms is presented. In this technique, the initial NURBS surface is generated by using object points as control points. Then, the genetic algorithm computes the weights and control ...
G1 continuity conditions of adjacent NURBS surfaces
For the special NURBS surfaces such as bicubic or biquartic B-spline surfaces with single interior knots, some results of the G^1 continuity conditions for two adjacent surfaces appeared recently. But for the NURBS surfaces with arbitrary degrees and ...
