Abstract

This paper proposes an effective method to select MIP-Map level of texture images for ray-traced texture mapping. This MIP-Map level selection method requires only the total length of intersected ray. By supporting MIP-Map for texture mapping, we can reduce the texture aliasing effects, while our approach decreases rendering performance very slightly.

본 논문은 광선 추적법 텍스쳐 매핑에서 MIP-Map 알고리즘 사용 시 텍스쳐 이미지들의 MIP-Map 수준을 선택하는 효과적인 방식을 제안한다. 이는 렌더링 시 물체와 교차하는 광선의 길이만을 사용하여 해당 물체의 텍스쳐 MIP-Map 수준을 선택하는 방법이다. 본 방식은 MIP-Map을 지원하지 않는 방식에 비하여 텍스쳐 알리아싱 면에서 우수하고 성능 저하는 미비하다.
