@perthvr Generally (not always) lighting that moves with the camera is doomed when it comes to 3D reconstruction, mainly because it messes with the feature point detection, the object is kind of a different object on each shot. As it happens no special lighting for this cave, it helped that I didn't need to do the entrance part of the cave, that is highly overexposed given I set the exposure for the interior. I was scrolling the exposure time as I was going around the cave to keep things balanced.
bit late off the mark but I just love the way you have been able to capture inside the cave where lighting would have been tricky did you use flash or other types of lighting such as strobe. oh and the shadows how did you manage those.cheers sally
Ah, now there's a capability I'd like to see, to be able to edit ones posts. The last line in my last comment should have read "...there are a number of other types of 3D data it is not so suited for."
Unfortunately I don't have any contacts there, I'm simply a "user" of their services like many other researchers.
But it would be nice to be able to embed 3D models from SketchFab, I imagine in a similar way as someone can now add datasets and additional images to the officially published paper.
The question you may need to address is "why SketchFab"? If ResearchGate were to provide 3D model support they may want a format that supports a wider range of capabilities and data types than SketchFab does, noting I'm not necessarily claiming such a thing exists. The main competitor that wold have been proposed say 5 few years ago would be 3D PDF but that has turned into the mess most of us expected to would.
So while I love SketchFab for textured meshes (although there are still features I'd like to see), there are a number of other types of 3D data it so suited for.
I saw your paper on ResearchGate. I work at Sketchfab and would like to partner with ResearchGate to let scientists embed 3D views on their platform. Do you have any contact there by any chance?

Hi Paul,

Thanks,

Bloody hell that's incredible
