Outline of Final Research Achievements

The purpose of this research is to generate and control free-form surfaces by taking account of the appearance by lighting and reflections. We clarified the parameters of log-aesthetic surfaces with good reflected shapes, and proposed interactive control methods. Also, we proposed complete log-aesthetic surfaces as an ideal class of surfaces. On discrete shade shapes created by diffuse reflection and cel shading, we clarified the mechanism of bending and waving, and proposed new shading algorithms to obtain simple and smooth shapes. We also obtained various results on shape processing techniques that improve appearance.
