随着计算机和计算机图形学的飞速发展,三维图像技术已广泛应用到各个领域。OpenGL,即开放图形库,是一个三维的计算机图形和模型库,由于本身与硬件环境和操作系统无关,使之成为功能强大的高性能开放式3D图形库。本文在理论研究的基础上,利用OpenGL在Visual C~(++)6.0平台实现了水平井井眼轨迹三维可视化,并通过光照渲染增强了三维显示效果,能对井眼轨迹实现缩放、平移、旋转等交互操作,为实现三维可视化地质导向钻井和可视化随钻测井资料解释打下了基础,具有较强实用价值。
With the rapid development of computer and computer graphics, three-dimensional image technology has been widely used in various fields. OpenGL, an open graphics library, is a three-dimensional computer graphics and model library that, thanks to its independence from the hardware environment and operating system, makes it a powerful high-performance open 3D graphics library. On the basis of theoretical research, this paper uses OpenGL to visualize the horizontal wellbore trajectory in Visual C ~ (++) 6.0 platform and enhances the three-dimensional display effect by light rendering. It can achieve the functions of scaling, translation, Rotation and other interactive operations, in order to achieve the three-dimensional visualization of geological-oriented drilling and visual logging while drilling data interpretation laid the foundation, with strong practical value.
