Abstract

Abstract: The article describes detailed construction’s algorithm of Bezier control points.It considers influence of flight route simulation and OpenSceneGraph（OSG） terrain data’s loading into memory or unloading from memory.The vector tool is used in describing algorithm.At the end，the experimental result shows the whole curve’s figure is good.

Key words: Bezier cubic curve, control point, flight route simulation, vector, terrain data’s loading into memory and unloading from memory

摘要： 针对模拟飞行路线的实际需求，考虑OpenSceneGraph（OSG）地形数据内存调度的影响，利用向量工具，对Bezier曲线的控制点给出一种构造设计算法，数值模拟实验显示了曲线的整体形状较好。
