Realization Of Modeling And Realtime Ramble Of Three-dimensional Road Sight

This paper discusses the method of creating road and sight model, observing model perspectively and dynamicly, processing and rambling it realtime.(1) This paper illustrates two methods of creating model on emphasis: one is based on AutoCAD,the other is based on Creator. For the former, author puts forward the theory of automatically creating road and sight model with ObjectARX, and programs to realize it. For the latter,author describes the parametrically creating method with the RoadPro module of Creator. (2) Author analyzes the theory of drawing perspective, author programs to draw perspective and observe it dynamicly.(3) This paper introduces how to process the model in Creator.(4) Finally, author discusses how to configure the Lynx panel, and how to program to realize realtime ramble.The innovation of this paper:(1) The road and sight model's resolvent based on ObjectARX is put forward.(2) For the first time,author introduces the famous software of America "Multigen——Creator" to create road model. Through this software, data can be converted to models directly without programme, so it is very convenient.(3) For the first time, Author attempts to apply the simulation software "Vega" to road simulation field.The production of this paper is significative. It can be applied in city layout ,road design, digital etc, for making perspective, movie and ramble system. It will promote the application of Creator and Vega in the field of civil engineering.
