Abstract

Recently, due to the rapid development of smart computing technology, there have been a lot of studies on 3D navigation, and consequently the advanced commercial 3D navigation system and 3D VTS system are on the market. Even the 3D technology is well known and wide spreaded, unfortunately, the secret of code behind is still unleashed. The purpose of this paper is to show the basic methodologies to display ENC features under 3D display environment to meet the requirement of S-52 standards. The OpenGL ES is used to develop 3D ENC Viewer for further use on mobile platforms and web based vessel monitoring system. P articularly, area object triangulation, complex line drawing, polygon pattern filling and symbol drawing by texture mapping are explained in detail. The result of performance test is shown as table for correlation of SENC file size to display speed.

최근 스마트 컴퓨팅 기술(IEEE, 2016)의 급격한 발달에 따라 3차원 항해시스템에 대한 연구가 활발해지고 있으며, 이를 적용한 상용 3차원 항해 시스템 및 3D VTS 시스템이 등장하고 있다. 비록 3차원 기술이 널리 알려지고 사용되고 있다 하더라도, 베일에 쌓인 숨겨진 코드에 대한 내용은 밝혀진 바가 없다. 본 연구의 목적은 S-52 전자해도 표현 표준을 만족할 수 있도록, 3차원 디스플레이 환경 하에서 전자해도 객체를 표현하는 기초적인 접근 방법을 보이는 것이다. 향후에 스마트폰 및 패드와 같은 모바일 기기에서도 사용하고, 웹기반의 선박관제시스템에도 사용할 수 있도록 OpenGL ES를 이용하여 3D ENC Viewer를 개발하였다. 특히 면객체 삼각화(area object triangulation), 텍스처 매핑에 의한 복합선 표현, 폴리곤 패턴 채우기, 심볼 작도 등에 대해 자세히 설명한다. 삼각화된 공간정보를 포함하는 시스템전자해도(System ENC)의 파일크기와 디스플레이 속도의 상관관계를 검토하여 성능을 검증하였다.
