Hi,

Not sure I understand exactly what you want to do, but one way would be to create a shape corresponding to each segment and interpolate the ImageData values onto them.

Please note that the following procedure uses the VolumeOfRevolution plug-in ([Help with Rotational Extrusion - #6 by jmisedam](https://discourse.paraview.org/t/help-with-rotational-extrusion/4840/6)).

1. Load the VolumeOfRevolution plug-in (Tools \> Manage Plugins…)
2. Create a disk with a hole corresponding to each segment (Disk Source)
3. Cut the disk with holes in half
4. Create a volume mesh by rotating the half disk (VolumeOfRevolution plug-in)
5. Integrate the volume mesh except for the core (AppendDatasets)
6. interpolate ImageData values into the volume mesh (ResampleWithDataSet)
7. put a value in Luminosity of the core volume mesh (Properties \> Lighting \> Luminosity)
8. ray traced rendering \> OSPray pathtracer

The State file used for the test has been uploaded.
