pretty photos, and nice work!
more than anything, though, thanks for introducing me to PlotOptiX! It looks like a great way to plot scientific data in 3D :D

Thanks to all for the feedback and comments!
@rcarmo Yes, bumps are enhanced, to make the surface more dramatic. This scale is a parameter in the notebook, it can be set to the realistic 1.15% of the mean radius.
On another forum, someone pointed out that the Lambertian shading makes the Moon surface too smooth. So the diffuse material roughness will come in the next PlotOptiX release, in a few days. :)

Maybe this help with: https://github.com/x3dom/x3dom
As I heard it's based on explicit DOMs.
Have anyone tried X3DOM?

The video is very nice, although the bump/displacement seems a little too strong - craters should look a little shallower :)
Do you use Lola data? What resolution and from where?
Yes, 118m resolution, it is from: https://astrogeology.usgs.gov/search/details/Moon/LRO/LOLA/L...
All other sources (surface color, star map in the background) are referenced in notebooks, gallery, and tutorial as well.

What hardware did you use to produce such photos?
PlotOptiX requires NVIDIA GPU. I used GTX1060/6GB on a laptop for most of the work. Tested also on a desktop RTX1070/8GB, much better fps, of course. Video is done on RTX. In Google Cloud, on V100, runs even faster, but GUI is more convenient on local machine.
Code can run on GCP instance. Laptop/desktop is more convenient, though.
