Abstract


As the world economy recovers , port construction, set off a new round of high tide , in order to improve the efficiency of port operations and reducing accidents, the port monitor virtual simulation developed gradually become popular . With the rise of 3D technology , port monitoring system phasing out the original two-dimensional rendering technology instead use three-dimensional graphics technology, the use of new technology not only makes the monitoring system has a new visual experience, but through multiple levels of optimization, a substantial increase in system performance. System uses a three-dimensional engine OGRE as a development platform, combined with input engine , physics engine, the port and port container lifting process dynamic simulation, monitoring. In order to improve the simulation results , the system adds Hydrax Caelum sky system, and marine systems , simulate the real environment around the ports and use 3DSMAX create panoramic harbor crane models and field ( yard cranes ) and crane ( shore crane ) model, the field cranes and crane for object-oriented modeling and functional division . For field cranes, bridge cranes and trolley carts moving discrete control data , the paper proposed interpolation algorithm based on velocity prediction to calculate the continuous motion path , so that the movement of trolley carts and more smoothly . And in order to simulate the effect crane tilting axis , the paper presents the IK inverse dynamics based on OGRE analytical method , real-time simulation of tilting IK linkage. In order to improve rendering speed , the paper proposes View_based LOD solutions , dramatically reducing the number of triangles rendered in real time , thus improving system performance. Experiments show that the Windows platform by using velocity-based interpolation forecasts , IK reverse dynamics analysis and perspective based LOD techniques , greatly improving the simulation results and operational efficiency , the development of three-dimensional simulation has some reference significance.
