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。
Using Fractal Technology to Realize Three Dimensional Dynamic Modeling in Virtual Route Selection Environment. The model can simulate the three-dimensional images of ground, background sky, trees and so on in the simulation system of railway route virtual environment. Compared with the traditional static modeling methods, this modeling method not only has high authenticity and diversity, but also has a very small effect on the movement speed of the entire three-dimensional scene. The method of dynamic modeling using fractal technology can achieve good visual effects. The proposed model can not only meet the requirements of three-dimensional railway dynamic modeling, but also can be applied to other three-dimensional scenes.
