摘要
从介绍世界坐标系和局部坐标系的转换关系出发,重点介绍了管网的直线部分建模和管网衔接处的光滑技术,提出了一种基于空间变换的技术来绘制管网,并运用一种新的曲线光滑算法实现了管网拐角处的光滑,该算法方便高效,能产生逼真的效果,并给出了加快三维显示速度的方法,实现了管网的大规模实时建模。
This paper discusses pipeline three-dimensional modeling techniques, at the begining, introductes the world coordinate system and the transformation between local coordinate system, focusing on the straight part of pipeline network modeling and smoothing at pipeline interface technology, a coordinate transformation based on Techniques to draw the pipe network, and use a new kind of curve smoothing algorithm at the comer of the pipeline is smooth, convenient and efficient algorithm that can produce realistic effects, and gives way to speed up the rate of three-dimensional display to achieve the management Network of large-scale real-time modeling.
