1. Why are all the Cinematic rendering examples on vtk.js based on webXR?
2. Volview( [https://volview.kitware.app/](https://volview.kitware.app/) ）Cinematic rendering don’t be based on webXR, right?
3. Based on webXR（ [vtk.js](https://kitware.github.io/vtk-js/examples/WebXRHeadFullVolumeCVR.html) ）The three examples use Volumetric Shading, Hybrid Shading, and Gradient Shading respectively. What’s the difference between them, the kind of shading used on Volview?

The vtk.js cinematic examples are just demos for both cinematic rendering and WebXR together. You are correct, cinematic rendering does not depend on WebXR, and VolView does demonstrate that.

Thank you for your reply, Forrest. You have been a great help to me.
Do you have detailed information or examples about vtk.js cinematic rendering?
I have already read this paper（ [https://doi.org/10.1080/21681163.2022.2145239](https://doi.org/10.1080/21681163.2022.2145239) ）The paper is really great.
Can I assume that Volumetric Shading and Gradient Shading are techniques in cinematic rendering?

Yep, those two shading techniques contribute to cinematic rendering. The details are all in that paper, and you can see how [VolView uses it in code](https://github.com/Kitware/VolView/blob/4dbb960324aee6673d0600c909a36366fd3b5832/src/components/vtk/VtkBaseVolumeRepresentation.vue#L71-L134).

Thank you, Thank you very much. Have a good day.
