摘要
在铁路线路三维场景中 ,存在着大量的对称物 ,如树木、亭子、栏杆等 ,大部分对称物都属于复杂地物 .以树为例详细阐述了铁路线路三维景观动态仿真系统中绘制对称物的一种更简易方法———十字交叉贴图法 .实践证明 ,该方法在三维场景的描述中具有一定的通用性 。
There are a lot of symmetry objects in the railway 3D sight, such as tree, georgette, and balustrade and so on. Most of them belong to complex objects. The tree is taken as an example to present a more simple method of drawing symmetry objects in the railway 3D sight dynamic imitation system, namely cross intersect method. The practice has proved that this method has a universal quality to a certain extent in describing 3D sight. Its thought also can be referenced in drawing other objects.
