本文介绍了解决vtk7.0在不支持OpenGL3.2的显卡上运行时出现崩溃的方法。通过分析vtkOpenGLRenderWindow.cxx文件中关于OpenGL版本的检查逻辑，指出需要显卡至少支持OpenGL3.2才能正常运行vtk7.0。

vtk7.0已经配置好，但在运行时奔溃。

这里写图片描述
打开安装解压目录下的…\VTKsourcecode\Rendering\OpenGL2\vtkOpenGLRenderWindow.cxx文件，在545行发现如下代码：

 if (!GLEW_VERSION_3_2)
      {
      if (!GLEW_VERSION_2_1 || !GLEW_EXT_gpu_shader4)
        {
        vtkErrorMacro("GL version 2.1 with the gpu_shader4 extension is not "
        "supported by your graphics driver but is required for the new "
        "OpenGL rendering backend. Please update your OpenGL driver. "
        "If you are using Mesa please make sure you have version 10.6.5 or "
        "later and make sure your driver in Mesa supports OpenGL 3.2.");
        return;
        }
      vtkWarningMacro(
        "VTK is designed to work with OpenGL version 3.2 but it appears "
        "it has been given a context that does not support 3.2. VTK will "
        "run in a compatibility mode designed to work with OpenGL 2.1 but "
        "some features may not work.");
      }
    else
      {
      this->SetContextSupportsOpenGL32(true);
      }
