Our team use the VTK 9.0 to build 3D program.

We find the following messages:

vtkOpenGLExtensionManager  
[VTK： vtkOpenGLExtensionManager Class Reference](https://vtk.org/doc/release/7.1/html/classvtkOpenGLExtensionManager.html#details)

# VTK/OpenGL Driver Information

[VTK/OpenGL 驱动程序信息 - KitwarePublic](https://vtk.org/Wiki/VTK/OpenGL_Driver_Information)

# OpenGL Extensions Viewer

#everestultimate

the vtkOpenGLExtensionManager and ‘VTK/OpenGL Driver Information’ only check function.

the glview/everestultimate need extra software to check it.

Do you provide a better message to check environment ?  
If the Graphics card support but the driver don’t support, any better operations?

That extension manager has been removed from VTK a long time ago. It only supported an old OpenGL version.

You can checkout how some of the testing for OpenGL support is done in [`vtkOpenGLRenderWindow::ReportCapabilities`](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx#L2200-2266) and [`vtkOpenGLRenderWindow::SupportsOpenGL`](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx#L2200-2266)

Thanks, it works well
