Sorry, please ignore the first question. I know what you mean right now. But, please look at the second question:<br>"Also, I notice that in the vtkSMUniformGridVolumeRepresen<div>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?"<br><br>Thanks,<br>

I didn't add a new proxy definition for "OpenGLVolumeTextureMapper3D". Instead, I change the definition for "VolumeFixedPointRayCastMapper" to something like that:<br><SubProxy><br>
<Proxy name="VolumeFixedPointRayCastMapper"<br><div><div class="Ih2E3d">
proxygroup="mappers"<br>
proxyname="<span style="color: rgb(255, 0, 0);">OpenGLVolumeTextureMapper3D</span>"><br>
</Proxy><br>
</SubProxy><br></div>It didn't work. <br>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:<br>
<SubProxy><br>
<Proxy name="VolumeOpenGLTexture3DMapper"<div class="Ih2E3d"><br> proxygroup="mappers"<br> proxyname="OpenGLVolumeTextureMapper3D"><br> </Proxy><br>
</div> <ExposedProperties><br>
<Property name="SampleDistance" /><br> </ExposedProperties><br></SubProxy><br>I am wondering if I understand you incorrect. <br>Also, I notice that in the vtkSMUniformGridVolumeRepresentationProxy.cxx file (Servers/ServerManager/), between line 100~117, there are some code specifically related to VolumeFixedPointRayCastMapper, do I need to change these codes too?<br>

"OpenGLVolumeTextureMapper3D" proxy? Look at the definition for<br>
"VolumeFixedPointRayCastMapper" (it's further down in the file).<br>
You'll need to add a similar one for the "OpenGLVolumeTextureMapper3D"<br>
proxy.<br>
