Has anyone ever heard of or know of a way to export an HDS point cloud scan to a flattened 360 spherical pano??

Yes there is a way, I worked on a project 5 years ago or so and the produced did that. Scanned and interior of a mine the we shot panos and they combined them in a lab a MIT. Interesting project. I don’t have any of the particulars though, I came to the project late.

Ben Kreunen works a lot with panos and point clouds, but IIRC he goes
the other way, he creates 3D-models from panoramas. See his work here:

Vincent,

It depends exactly what you mean.

Faro SCENE software will generate an image directly from point cloud data. Example here:-


The quality will depend on the scanner used.

I'm not sure what you're asking for, but as a point cloud is essentially a 3d model I guess you're asking if you can make a pano from a 3d model? Indeed you can! Most 3d programs/renderers have a spherical camera which will output a standard equirectangular flat pano. In my tool chest I can do it with Lighwave or Sketchup/Thea render. I'm sure you could use free apps like Blender too. And if the program does not have such a camera you could still make a series of stills and stitch them with PTGui. No parallax and no lens distortion:-)
Another question is how to make such a point cloud interesting to look at.. You'd need to cover it with a mesh of triangular polygons, and eventually apply texture to them from photographs. I have never used a. 3d scanner, but I have made many panos from 3d models. And also made photogrammetric 3d models from series of photos, which is kind of similar to 3d laser scanning. But then you already have the photos for texturing, on models that have much less dense clouds.

1. Take this with cinema4d
https://cinemaplugins.com/c4d-plugins/lazpoint/
and a Pano render pluging from cineversity CV-VRCAM
and you get a Equirectangular Image from any pointcloud

I don't know if you can load it into Octane oder Vray within C4D

Just a little link to Blender cameras info :

And here is a 10 years old panorama virtual exhibition I made in 3d with Java viewer, if you can still make it work ;-)
