[Paraview] plugin error

[胡健]

hello my friend:

I want to add vtkOpenGLHAVSVolumeMapper to paraview as a plugin! I follow
the example in paraview for adding representation,but when I run paraview
and load the plugin and open a data, the program gives me an error message

"ERROR: In
..\..\..\ParaView-3.8.1\Servers\ServerManager\vtkSMProxyManager.cxx, line
369 vtkSMProxyManager (0BC34AB8): No proxy that matches: group=mappers and
proxy=OpenGLHAVSVolumeMapper were found.

ERROR: In ..\..\..\ParaView-3.8.1\Servers\ServerManager\vtkSMProxy.cxx, line
1979 vtkSMSourceProxy (13476AF0): Base interface cannot be found.".

do you know what's wrong with it?any help will be appreciate! thank you!
