摘要
通过分析Direct3D所能识别的数据文件(.X文件)格式,编程实现组织数据得到.X文件,快速自动生成三维巷道模型。并针对巷道拐弯处的圆滑问题,采用了改进的B样条曲线插值算法。实验表明,基于曲线插值算法的巷道自动建模,比建模软件建模易推广且运行速率高。
By analyzing data file （.X file） format recognized by Direct 3D, this article achieves.X file write realized from organizing data by program, fast automatic generation of three-dimensional laneway model. Besides, the article, aiming at smooth problem at laneway comer, uses improved B-spline curve interpolation algorithm. It is demonstrated by the experiment that modeling by the automatic generation of laneway model based on curve interpolation algorithm is much easier to promote and has higher operating speed than that of the modeling software.
