基于分形技术的铁路选线虚拟环境三维动态建模方法

运用分形技术实现虚拟选线环境中的三维动态建模。所建模型能在铁路选线虚拟环境仿真系统中模拟地面、背景天空、树木等的三维图像。与传统的静态建模方法相比,这种建模方式不仅具有较高的真实性和多样性,而且对整个三维场景的运动速度影响非常小。运用分形技术进行动态建模的方法能够取得很好的视觉效果,所建模型不但能够满足铁路三维动态建模的要求,还可以应用到其它三维场景中。

3D Dynamic Modeling Method for Railway Route Selection in Virtual Environment Based on Fractal Technology

Fractal technology is adopted to realize the dynamic 3D modeling in the virtual environment of route selection. This model can simulate 3D images of ground, background of sky, trees, etc. Comparing with the traditional static modeling method, this modeling method not only has higher authenticity and variety, but also has little influence on the moving speed of the whole 3D scene. Research indicates that the dynamic modeling method by fractal technology can make very good visual effect. The built model both can meet the demand for 3D dynamic modeling for railway and can be applied to other 3D scenes.
