摘　　要：为真实模拟岸边集装箱起重机的工作过程及环境,依据其工作特点构建视景仿真系统。基于Multigen Creator软件,应用图像缓存、纹理贴图、实例化模型的建模技巧创建岸边集装箱起重机及其场景模型,应用多层次模型和删除背面多边形的方法优化模型数据库;通过驱动岸边集装箱起重机DOF节点实现大车和小车的运动,通过控制其绳索伸缩实现吊具起升运动;采用Vega Path工具和Vega Marine模块分别创建集装箱运输车路径及动态海洋,基于VC++平台调用Vega库函数实现集装箱运输车和海洋的运动。通过开发岸边集装箱起重机视景仿真系统,实现岸边集装箱起重机现场工况的三维数字化。How to simulate a container crane working at coast-side surroundings in 3-D digitization.In order to actually simulate a container crane's operating process in coastside surroundings we constructed a simulation system for the visual field as based on the crane's working features.Again,we based on software Multigen Creator to have built a model for such a crane together with its background before optimizing the model's database,while driving the crane's DOF pitch points to have realized lift operation of the hoist and the trolley by wind-in and wind-out the ropes.At the same time we utilized tools Vega Path and module Vega Marine to have constructed modeling of the handling trucks' traveling path versus an acting sea,i.e.,operation of the crane versus motion of the sea as based on VC++ platform wile utilizing functions in Vega base,thus realizing a 3-D digitization of such a crane with its at-site working conditions.
