Thanks for your help.<br>I have tried to change "FixedPointVolumeRayCastMapper to something else" in the XML file. However, it still didn't work. <br>I am pretty new to these XML files. To the best of my knowledge, I changed the XML file to:<br>
<SubProxy><br> <Proxy name="VolumeFixedPointRayCastMapper" <br> proxygroup="mappers" <br> proxyname="OpenGLVolumeTextureMapper3D"><br> </Proxy><br>
</SubProxy><br>I simply delete the "ExposedProperties" part for this mapper, because I don't know how to decide which property should be exposed.<br>After those changes, I opened the iron_protein.vtk data with paraview. Here is the error message I got:<br>
<br>Unhandled exception at 0x0519e423(vtkPVServerManager.dll) in paraview.exe: 0xC0000005: Access violation reading location 0x00000000.<br><br>Is that because the proxyname is wrong? Or do I ｈａｖｅ ｔｏ ｅｘｐｏｓｅ ｓｏｍｅ ｐｒｏｐｅｒｔｉｅｓ？<br>

perfectly fine for that). I believe Biao is taking about image data<br>
volume rendering.<br>
