The question is what I want to ask.
How to fix results when rendering CPU usage?
Thanks a lot.

The above place in the documentation details Volume Rendering options associated with quality such as “Adaptive” and “Normal”.

@jamesobutler Thank you for your answer

cpuMapper->SetSampleDistance(displayNode->GetSampleDistance());
cpuMapper->SetInteractiveSampleDistance(displayNode->GetSampleDistance());

I see there are two parameters as above. So what is their input value usually and what is their meaning?

This is the sampling distance for raycasting. Higher number means coarser sampling, lower quality, higher speed. See more details in the VTK textbook and VTK documentation.
