[Paraview] Changing the default volume mapper in Paraview?

[Biao She]

Thanks for your help.
I have tried to change "FixedPointVolumeRayCastMapper to something else" in
the XML file. However, it still didn't work.
I am pretty new to these XML files. To the best of my knowledge, I changed
the XML file to:
<SubProxy>
        <Proxy name="VolumeFixedPointRayCastMapper"
          proxygroup="mappers"
          proxyname="OpenGLVolumeTextureMapper3D">
        </Proxy>
 </SubProxy>
I simply delete the "ExposedProperties" part for this mapper, because I
don't know how to decide which property should be exposed.
After those changes, I opened the iron_protein.vtk data with paraview. Here
is the error message I got:

Unhandled exception at 0x0519e423(vtkPVServerManager.dll) in paraview.exe:
0xC0000005: Access violation reading location 0x00000000.

Is that because the proxyname is wrong? Or do I ｈａｖｅ ｔｏ ｅｘｐｏｓｅ ｓｏｍｅ
ｐｒｏｐｅｒｔｉｅｓ？
