In your pipeline you ran a filter to extract the outer geometry rather than doing Volume rendering directly (assuming that is what you are trying to do).

Thanks @jourdain I’m referring the examples and the online VTK class reference and they are helpful. I started with VTK from VTK-JS and now exploring Trame. So was comparing VTK-JS functions available in Trame and facing some difficulty there. Exploring more in to it.

Initially I rendered the volume directly but was only able to see outside box. Then was trying to extract shape fr which that filter was included. Will check again if I can get it work.

Hi, just for update I was able to render the vti file in required representation after changing the mapper from vtkDataSetMapper to vtkFixedPointVolumeRayCastMapper.
