High-Quality Shape Fitting for Aesthetic Modeling Based on Class A Condition

ABSTRACT: In this paper, we propose a method of obtaining high-quality shapes from point clouds. We adopted the “Class A” concept, which has been defined as a shape that is monotonic in its curvature. Such high-quality shapes are preferred in product styling; therefore, an efficient method for their generation will be helpful in the style design process. The proposed method is based on a subdivision surface technique, the Class A definition, and a genetic algorithm. The proposed method is tested on some examples of surface generation, and the results demonstrate the effectiveness of our approach.
