Along with world economics' recovery, the port and harbor construction raises a new round of climax, to enhance the efficiency of the harbor operation as well as to reduce safety incident, the harbor's simulation and monitor e a popula rity in research. Along with 3D technology's spring up, the harbor supervisory syst em gradually eliminate the primitive 2D technology to transfer uses the 3D technol ogy, the new technology's use not only enabled the system to have a brand-new vi sual experience, but also simultaneously enhanced system's performance largely by using many optimizations.
The system uses the OGRE 3D engine to develop, union with the input engi ne and the physical engine, dynamicly simulate and monitor the harbor container's hoisting process and theharbor's changes. In order to improve the more simulation effect, the system increased the Caelum sky system and the Hydrax sea system, si mulates the real harbor peripheral environment,using the 3DSMAX to model RTG and QC , uses the way of object-oriented modelling to create RTG and QC's modl es as well as to partition their the controlling data of the RTG a nd the QC's mechanism as well as dan is discrete,so this thesis proposed an algori thm named BVIR which make the motion more ession. Simultaneously to simu late to the pitching‘s axis linkage effect of the QC, the thesis proposed a reverse dynamics analysis method based on the OGRE IK, real-time simulation pitching’s I K order to raise system's exaggeration speed, the thesis proposed a LOD solution which based on the angle of view, large reduced the exaggeration real-ti me triangle surface number, thus enhanced system's performance.
Experiments show that by using forecasts based on the speed of interpolation and IK inverse dynamics analysis as well as perspective-based LOD techniques in the Windows platform, greatly improving the simulation’s performance, it have has some Significant reference to the development of
