Could VTK be used to re-construct colorful 3D using colorful CT images?

I don’t know where to set IndependentComponents = flase. Could you help to change the code directly?

I use the CT to generate gray images which are then used to generate colorful images. The generated images are dicom format. I could read and display the colorful dicom images using pydicom successfully.

By the way, if Slicer you mentioned works for my colorful images, I am willing to try it. however I could not access it. Perhaps, there is something wrong with my network.

The following image is the dicom file plotted in pydicom:
