Abstract

Global illumination is key factor for realistic image but it is not common in realtime rendering due to its complexity. Visibility of $2^{nd}$ lights is hard to determine because we should process all object for each $2^{nd}$ light. In this paper, we reuse visibility of static objects. We present an indirect illumination algorithm which shows good performance and provides exact $2^{nd}$ light visibility when the scene has small number of moving objects. Our method renders correct image while showing good performance.

간접조명은 실제감에 많은 도움을 주지만 많은 계산량이 필요하기 때문에 실시간 전역조명에서는 적용되기 힘들었다. 특히 2차광원에서의 가시성을 계산하기위해서는 각 광원에 대해서 모든 물체들을 처리해야 하기 때문에 계산량이 많다. 본 논문에서는 움직이지 않는 물체들의 가시성을 재활용하여 움직이는 물체가 많지 않을 경우 효율적이면서도 2차광원의 가시성을 활용하는 간접조명 알고리즘을 제안한다. 기존 방법에 비해서 정확하면서도 효율적인 2차광원 가시성을 바탕으로 보다 복잡한 장면에서 사실적인 간접조명을 실시간에 가능하게 한다.
