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!
