摘要：

为满足数据显示方式多样化的需要,基于VS2008开发环境和MFC应用程序框架,利用OpenGL丰富的三维图形绘制功能和颜色渲染功能生成漏磁数据的三维视图。实际测试结果表明:三维视图能够精确、直观地反映数据变化的真实性,辨识度高,颜色过渡效果理想,增强可读性和分析效率,对管道缺陷的识别与判断具有重要意义。

Abstract: To meet the needs of various data displays, the paper used abundant three-dimensional drawing functions and color rendering capabilities of OpenGL to generate a three-dimensional view based on VS2008 development environment and MFC application framework. The actual test results has proved that the three-dimensional view could accurately and intuitively describe real change of the MFL data with high definition and ideal color transition effects and thus enhance readability and efficiency of the analysis, which is vital for defect recognition of the pipeline.
