| Abstract |
| Many kinds of computer graphic softwares have been developed since the use of computer was introduced to arts area as well as technology. Above all, three-dimensional computer graphics has developed dramatically in both quality and quantity. In order to effectively use three-dimensional computer graphics that is divided into NURBS surface system and polygon surface system by modeling system, the study suggested characteristics, functions, usages, and merits and demerits of the two modeling systems and extracted problems occurring from modeling process. And for edge rounding, it presented solutions through procedures as below. First of all, the necessity of edge rounding for reality of outcome is suggested. Secondly, the functions and applying systems of edge rounding provided by each softwares are presented and analyzed. Thirdly, the concept of low polygon is applied for edge rounding in polygon modeling. Fourthly, the function of Mesh Smooth is understood and applying systems for edge rounding is presented. Even though sometimes required software is decided according to the usage of modeling and convenience of operation, it is necessary to recognize that user`s standard to choose software involves realistic conditions such as economical efficiency, compatibility and perception as well as usage and convenience. Finally, it is most important to find out the system to minimize demerits of each modeling system. |
