초록

이 논문에서는 모바일을 기반으로 하는 사진 트리 영상 랜더링을 통하여 효율적인 PDA 용 전자의 무기록(EMR ; Electronic Medical Record) 챠트를 제안하였다. 볼륨 렌더링을 위하여 최종 영상 공간 대신에 중간 영상 공간 공간 알고리즘을 사용하였고, 점 대 점 매핑으로 발생하는 Hole의 문제점을 해결하였다. 델타 트리 기반의 quad 트리를 사용함으로 볼륨 표현에 효과적이었고, 압축 효과가 높았다. 볼륨 렌더링을 사용하여 렌더링의 시간을 줄일 수 있었고, 영상기반 렌더링(image-based rendering) 을 이용한 PDA 를 사용하여 질적 향상과 효율화를 얻게 되었다.

This paper presents an EMR(Electronic Medical Record) chart for efficient PDA through the quad tree image rendering based on the mobile. Using the intermediate image space algorithm instead of the final one for volume rendering, we have solved the probems of th eholes coming from the point-to-point to mapping. The quad-tree based on the delta-tree efficiently represents volume expressions and results in higher compression effects. With the volume rendering, we can decrease the rendering time and get a higher quality and efficiency for PDA through image based rendering.
