Abstract

3D 가상 장면을 복수의 격자들을 이용하여 구분하고, 광원으로부터 방출된 복수의 광선들이 3D 가상 장면 내에 위치한 하나 이상의 객체에 입사하는 복수의 제 1 지점들 및 복수의 제 1 지점들을 포함하는 복수의 제 1 격자들의 위치 정보를 획득하고, 복수의 제 1 지점들에서 반사된 복수의 광선들이 하나 이상의 객체에 입사하는 복수의 제 2 지점들 및 복수의 제 2 지점들을 포함하는 복수의 제 2 격자들의 위치 정보를 획득하고, 복수의 제 1 격자들의 위치 정보 및 복수의 제 2 격자들의 위치 정보에 기초하여 복수의 격자들 각각의 조도를 결정하는 방법이 개시된다.
