초록
본 논문에서는 2-변수 모션 (two-parameter motion)을 이용한 새로운 스윕곡면의 생성 및 편집기법을 제시한다. 먼저, 하나의 변수로 매개화되는 기존의 모션에서 방향곡선 (orientation curve)과 크기변환곡선 (scaling curve)을 곡면의 형태로 확장한 2-변수 모션의 개념을 소개하고, 이를 이용한 새로운 스윕곡면을 제안한다. 제안된 스윕곡면은 하나의 정점이 2-변수 모션에 적용된 결과이며, u-방향의 등위곡선 (iso-curve)이 매개변수 v에 따라 다른 형상을 갖게 된다. 또한 이에 대한 효율적인 모델링 및 편집기법은 2-변수 모션의 직관적인 제어를 통해서 이루어진다. 본 논문에서는 복잡한 형상에 대한 모델링 및 편집 실험을 통해서 제안된 기법의 효율성 및 편리성을 입증한다.
Abstract
We present a new technique for constructing a sweep surface using two-parameter motion. Firstly, a new rational B-spline motion with two parameter is introduced, which is obtained by extending its orientation curve and scaling curve to surface counterparts. A sweep surface is then defined by a single vertex v under the two-parameter motion and allows to represent different u-directional iso-curves depending on parameter v. Efficient techniques for modeling and editing the surface are achieved by intuitively controlling the two-parameter motion. We demonstrate the effectiveness of our technique with experimental results on modeling and editing a 3D propeller model.
