Abstract

2D input data have to be converted into 3D data by means of some functions and menu system in 2D input modeling system. But data in 3D input system for virtual spatial design can be directly connected to the 3D modeling data. Nevertheless, efficient surface modeling and deformation algorithm for the 3D input modeling system are not proposed yet. In this paper, problems of conventional NURBS surface deformation methods which can occur when applied in the 3D input modeling system are introduced. And NURBS surface deformation by 3D target curves, in which the designer can easily approach, are suggested. Designer can efficiently implement the virtual spatial sketching and design by using the proposed deformation algorithm.

2차원 평면 입력을 통한 모델링에서는 입력 값을 3차원 데이타로 바꾸기 위한 기능과 메뉴들이 필요하지만 가상공간 디자인을 위한 3차원 입력 시스템은 입력 값을 곧바로 3차원 데이타로 변환될 수 있다. 하지만 3차원 입력시스템에서 효율적인 곡면 모델링 방법, 특히 곡면 변형 방법은 제안되지 않고 있다. 본 논문에서는 기존의 변형방법이 3차원 입력시스템에서 적용되었을 때 발생할 수 있는 문제점을 제시한다. 그리고 디자이너가 접근하기 쉬운 목표곡선을 이용한 변형을 제안한다. 이와 같은 3차원 목표곡선을 이용한 변형을 통해 디자이너가 보다 쉽게 3차원 입력시스템에 접근하여 가상공간 스케칭 및 디자인을 구현할 수 있다.
