基于OpenGL的地形三维可视化研究

STUDY ON 3D TERRAIN VISUALIZATION BASED ON OPENGL

利用OpenGL开放图形库的200多个函数,在前人对三维可视化研究的基础上,基于实际生产中的需求,提出一种可行的“二次简化法”。实践证明,这种处理方法能够使生产出的三维地形图在兼顾高度逼真的同时,能够实际地处理空间分析操作运算,满足了生产中的需要。

This paper, based on the two hundred of functions in OpenGL and many forerunners＇ experience in 3D visualization, presents a feasible method named ＂Bis Predigestion＂, which can produce the most realistic 3D terrain and complete the 3D spatial operation, meeting the needs in production.
