摘要
想要实现船舶操纵模拟器视景仿真时,为了获得良好的仿真效果,就需要建立大量的、充分有效的、贴近实际的三维模型。本文根据视景仿真数据库的功能需求,构建灯塔和浮筒、码头缆桩和装卸机械、码头的仓库和典型建筑、城市背景和岛屿、沿岸山形等船舶操纵模拟器典型三维模型。模型建好后,通过包围盒碰撞检测技术,对操纵模拟器不同场景的包围盒结构的遍历,满足船舶操纵模拟器碰撞检测的实时性要求,较好地实现复杂海况下视景仿真的碰撞检测。
To obtain well simulation results,a large number of 3d models need to be built in the implementation of visual scene simulation system of ship handling simulator.Based on the functional requirements of visual simulation database,the lighthouse and float cylinder,wharf mooring bitt and handling machinery,wharf warehouse and typical architecture,city background and island of ship handling simulator typical 3D virtual scenes were established.After establishing the 3D virtual model,the bounding box collision detection algorithm is improved to traverse the bounding box structure of ship handling simulator different Scenes to achieve the real-time requirements of Ship Handling Simulator collision detection.better implementation of collision detection under complicate sea conditions Scene Simulating.
