Abstract

Due to the continuing technical progress in the capabilities of modeling, simulation, and sensor devices, huge volume data with very high resolution are common. In scientific visualization, various interactive real-time techniques on high performance parallel computers to effectively render such large scale volume data sets have been proposed. In this paper, we present a mobile volume visualization system that consists of mobile clients, gateways, and parallel rendering servers. The mobile clients allow to explore the regions of interests adaptively in higher resolution level as well as specify rendering / viewing parameters interactively which are sent to parallel rendering server. The gateways play a role in managing requests / responses between mobile clients and parallel rendering servers for stable services. The parallel rendering servers visualize the specified sub-volume with rendering contexts from clients and then transfer the high quality final images back. This proposed system lets multi-users with PDA simultaneously share commonly interesting parts of huge volume, rendering contexts, and final images through CSCW(Computer Supported Cooperative Work) mode.

모델링 시뮬레이션 그리고 센서 장비 기술의 지속적인 발전으로 최근에 매우 높은 해상도를 갖는 방대한 크기의 볼륨 데이타들이 일반화되고 있다. 과학적 가시화 분야에서, 이러한 데이타를 고성능 병렬 컴퓨터를 사용하여 효과적으로 가시화하기 위한 다양한 대화식 실시간 기법들이 제안되어 왔다. 본 논문에서는 모바일 클라이언트, 게이트웨이, 병렬 렌더링 서버로 구성되는 모바일 볼륨 가시화 시스템의 개발에 관해 설명한다. 모바일 클라이언트는 병렬 렌더링 서버에게 전달할 렌더링 / 뷰잉 파라미터를 설정할 수 있는 기능뿐만 아니라, 관심이 있는 특정 영역을 점진적으로 높은 해상도의 영상을 이용해 탐색할 수 있는 기능을 제공한다. 게이트웨이는 안정적인 서비스를 위해 모바일 클라이언트와 병렬 렌더링 서버 사이에서 주고받는 요청과 응답을 관리하는 역할을 한다. 병렬 렌더링 서버는 클라이언트로부터 전달받은 렌더링 컨텍스트를 이용하여 정의된 특정 부분 볼륨을 가시화하고, 고해상도의 최종 영상을 클라이언트에게 되돌려 주는 작업을 수행한다. 제안된 시스템은 PDA를 갖고 있는 여러 사용자가 협력작업(CSCW) 모드를 통해 동시에 볼륨 데이타 가운데 공통으로 관심을 갖는 특정 부분, 렌더링 컨텍스트, 그리고 최종 영상을 공유할 수 있도록 설계되었다.
