초록
본 논문에서는 영상 기반 모델링과 랜더링을 위한 방법을 다룬다. 삼차원 그래픽스를 위해서는 기본적으로 물체의 기하학적 3차원 형상 데이터와 물체 표면의 색깔 및 빛의 반사특성을 알아야한다. 어떤 실제 물체의 삼차원 기하 정보 와 반사 정보는 그 물체의 영상에 이미 담겨있으므로 이를 랜더링에서 어떻게 사용하는가에 따라 그 모델링 방법이 달 라진다. 본 논문에서는 영상기반 모델링 및 랜더링의 많은 방법 중에서 특히 국내에서 개발된 것들을 중심으로 영상을 이용하여 어떤 물체의 기하 정보 및 조명 정보, 반사 정보를 얻는 방법에 대한 기술적 동향을 알아본다.
Abstract
This paper introduces recent methods of image-based modeling and rendering (IBMR). Fundamental requirements for the synthesis by 3D computer graphics are the geometric shape information of an object and its reflectance property on the surface. Because the information of geometric shape and reflectance is contained in the images of the object, the method of rendering decides its own modeling technique. This article presents some international quality results of IBMR researches having been done especially in Korea. Presented is technological trends in obtaining information of geometric shape and reflectance property of an object from its images as well as in finding the information of illumination environment.
