摘要
三维真实感图形是科学可视化、计算机动画和虚拟现实的关键技术之一.介绍了利用OpenGL绘制三维立体图形的方法,充分利用OpenGL的库函数进行了三维场景的绘制、渲染和纹理映射,绘制了真实的三维立体图形,并提供了一些从不同侧面和角度观察所绘图形的方法.软件在Winows2000/VisualC++6.0下开发,采用窗口的切分功能扩大视图范围,可提供不同的颜色背景和不同的视角进行观察,也可以对图形进行渲染和绕任意轴旋转.
The method of drawing 3D graphics based on OpenGL is introduced. The drawing, coloring and texture mapping of 3D graphics can be conducted by means of the library functions of OpenGL. some methods and approaches to view the drawn graphics from different angles are presented. The software for drawing 3D graphics is developed under Windows2000/Visual C+ + 6. 0, it is mainly composed of 3D window, color window, pantagraph window, file design, template design etc. modules.
