Thank you @Rafael_V_Monteiro for sharing this valuable project 👍

Yes, this is a very interesting aspect of the data and worth visualizing. I think the new ColorizeVolume method would be good with this data and you could use it to make movies to accompany the 3D surface models. If we like it, it should also be possible at some point to port this method to run natively in the browser.

We’ll need to do the local smoothing / surface fitting in the GPU using the segmentation and the color from the lookup table. This should be effectively the same as building a surface model but faster and with some extra options. I agree we should think about how we should handle volume rendering from a UI perspe…
