In that case simply remove the command attribute from the LockSampleDistanceToInputSpacing property. That way ParaView will not try to call that method on the vtkOpenGLVolumeTextureMapper3D class.

Re: [Paraview] Changing the default volume mapper in Paraview?
I know it's kind of hacky, but you can simply edit the XML file and change the mapper used. Look at Servers/ServerManager/Resources/rendering.xml. In the XML for UniformGridVolumeRepresentation change FixedPointVolumeRayCastMapper to something else. Then after the definition for FixedPointVolumeRayCastMapper, add a new definition for the VolumeTextureMapper3D and use that in the UniformGridVolumeRepresentation. I am not sure it's going to work out of the box. But work a try. Utkarsh On Wed, Feb 18, 2009 at 6:42 PM, Biao She sheb...@gmail.com wrote: Hi everyone. I have debugged paraview for days.

The combo-box is only for unstructured volume rendering (and works perfectly fine for that). I believe Biao is taking about image data volume rendering.

Re: [Paraview] Changing the default volume mapper in Paraview?
Thanks very much for your help, Utkarsh. The OpenGLVolumeTextureMapper3D works right now. Just for future reference, here are instructions to make a volume mapper available in paraview: 1. open the rendering.xml file at the /$Paraveiw-Source-Directory/Servers/ServerManager/Resources directory. 2. copy the SourceProxy definition of FixedPointVolumeRayCastMapper, paste it after the definition and made the following changes: (the bold ones are the places where I made changes ) SourceProxy name=*OpenGLVolumeTextureMapper3D* class=*vtkOpenGLVolumeTextureMapper3D* InputProperty name=Input command=SetInputConnection DataTypeDomain name=input_type DataType value=vtkImageData/ /DataTypeDomain /InputProperty StringVectorProperty name=SelectScalarArray command=SelectScalarArray number_of_elements=1 animateable=0 ArrayListDomain name=array_list attribute_type=Scalars RequiredProperties Property name=Input function=Input/ /RequiredProperties /ArrayListDomain /StringVectorProperty IntVectorProperty name=ScalarMode command=SetScalarMode default_values=3 number_of_elements=1 animateable=0 EnumerationDomain name=enum Entry value=0 text=Default/ Entry value=1 text=PointData/ Entry value=2 text=CellData/ Entry value=3 text=PointFieldData/ Entry value=4 text=CellFieldData/ /EnumerationDomain /IntVectorProperty IntVectorProperty name=LockSampleDistanceToInputSpacing command=SetLockSampleDistanceToInputSpacing default_values=1 number_of_elements=1 animateable=0 BooleanDomain name=bool / /IntVectorProperty !-- End of FixedPointVolumeRayCastMapper -- /SourceProxy 3. find the SubProxy of VolumeFixedPointRayCastMapper, make the following change (bold): SubProxy Proxy name=VolumeFixedPointRayCastMapper proxygroup=mappers proxyname=*OpenGLVolumeTextureMapper3D* /Proxy ExposedProperties Property name=LockSampleDistanceToInputSpacing / /ExposedProperties /SubProxy 4. find the header file of vtkOpenGLVolumeTextureMapper3D at the /$Paraveiw-Source-Directory/VTK/VolumeRendering/ directory. add *vtkSetClampMacro( LockSampleDistanceToInputSpacing, int, 0, 1 );* as public method, add *int LockSampleDistanceToInputSpacing;* as a protected variable. 5. compile your program and go. I understand that vtkOpenGLVolumeTextureMapper3D mapper doesn't need a property of LockSampleDistanceToInputSpacing, but this is the fastest way for me to make the mapper works. Any clue about how to get rid of the variable? Thanks again for all the helps!

I'll leave that as is so the vtkSMUniformGridVolumeRepresentationProxy will just work. On Thu, Feb 19, 2009 at 4:33 PM, Biao She sheb...@gmail.com wrote: Sorry, please ignore the first question. I know what you mean right now. But, please look at the second question: Also, I notice that in the vtkSMUniformGridVolumeRepresen tationProxy.cxx file (Servers/ServerManager/), between line 100~117, there are some code specifically related to VolumeFixedPointRayCastMapper, do I need to change these codes too?

Instead, I change the definition for VolumeFixedPointRayCastMapper to something like that: SubProxy Proxy name=VolumeFixedPointRayCastMapper proxygroup=mappers proxyname=OpenGLVolumeTextureMapper3D /Proxy /SubProxy It didn't work. By now, I have tried to add a new proxy definition for OpenGLVolumeTextureMapper3D, but I got the same error message. The following is the XML proxy I wrote: SubProxy Proxy name=VolumeOpenGLTexture3DMapper proxygroup=mappers proxyname=OpenGLVolumeTextureMapper3D /Proxy ExposedProperties Property name=SampleDistance / /ExposedProperties /SubProxy I am wondering if I understand you incorrect.
