摘要
介绍了V.Dragon 2000分布式航海仿真系统的体系结构和采用的图形技术:视景生成技术、雷达图象生成和电子海图显示技术。从仿真系统的实时性和真实感的角度出发,着重介绍了视景生成技术中基于海浪谱的不同浪级海面的仿真模型、基于粒子系统和图象合成的船舶航迹流仿真模型和基于海图等高线数据的三角优化构网算法,这些算法可实现海面和船舶航迹流的实时动态仿真,并可自动实现真实港口的地貌建模,方法简单、实用。
The paper introduces the architecture and graphic technology such as: visual technology, radar image generation and electronic chart displaying method used in distributed marine simulation system: V. Dragon 2000. The simulation model of sea based on energy spectrum of wave is described in details. The model can simulate various sea states in real-time and generate realistic scene. Particle system and image synthesis method are also adopted to implement the dynamic simulation of ship抯 wakes in real-time. Triangulated algorithm is used to generate the optimized triangular mesh based on the contour line in a sea chart; the algorithm can generate the 3-D surface model of a real harbor.
