The Design And Realization Of Ship Attitude And Route Base On Virtual Reality Technology

How to control the ship's posture and routers to make sure it can reach the port on time,now has become an urgent problem need to address.therefore,people have carried a series of explorations.Now,with rapid development of computer science,it provide an effective means for us to study the shipping movement and posture by virtual reality technology.This paper achieve the simulation of shipp's posture and routers,especially in deep sea,base on virtual reality technology.Firstly,the paper discuss the development of ship and introduce the technologies,such as visual simulation technology,the three modeling techniques,Generate real-time animation technology and visual production and display technologies,also it sum up the development and direction of virtual reality technology.Secondly,this paper analyse software platform for more detail.during the establishment of the system,the paper employe 3DS MAX to modeling,to make the model more visual, we use photoshop to process the texture.Considering establishment of the system base on Visual Studio.net compiler and D3D,we take a brief introduction about VC++ and COM,espacially,the paper analysis D3D framework on detail to make full preparations for systems development.Thirdly, the paper ,espacially,take a detail analysis and design on seawave algorithm,it offer two algorithms:cosine superposition algorithm and iWave and optimize the latter,and then compare with each other.Finally,the paper introduced the methods of establishing ship's motional model, then emphasized on the discussion and ananysis of the separate types(MMG)ship's motional model,especially for its parameter calculation,at last,this paper puts forward a solution for System Motion Simulation and present the real-time display results about ship's attitude.
