       | I know we're just supposed to upvote here, but this is too
       | amazing not to praise. Beautiful work.

         | Just so fascinating; and I find these kinds of scenes a little
         | spooky.

       | This looks so cool, and unlike anything I've ever seen before.
       | Great work!

       | Excellent. Reminds me of some non photorealistic renderings from
       | the 00's. Quake NPR with pencil rendering was cool.

       | Sounds complicated, to be honest. Could this not be achieved
       | easier via monocular depth estimation, for example?

         | Informative-Drawings already has monocular depth estimation
         | built in--that's why its line results are so beautifully
         | consistent. But without this extra step combining results from
         | multiple camera positions, you get 2.5D geometry, not 3D.

         | The soft colors reminded me more of Valkyria Chronicles:

       | I was dazzled with the drawing itself. Then by accident I
       | discovered you can zoom in and out too. And on top of that - you
       | can also rotate 360 degrees around the object.
       | 
       | Too far out of my field for me to understand how impressed I
       | should be - but I am impressed.

       | This is super creative. For those who like to reduce their
       | experiences of fun cool stuff, I'll describe it: Implement a line
       | drawing-on-2D algorithm that maintains geometry on a particular
       | 2d view. Run each of your source images for a Gaussian splat
       | through the line drawing tool. Use those 2d line images to make
       | your splat.
       | 
       | Result: a 3d scene that can be posed and shows as a 2d line
       | illustration.
       | 
       | I like a lot of things about this, but mostly I like the facility
       | demonstrated here, and the experimentation. So many interesting
       | things to do are in hobbyist reach right now, it's kind of
       | breathtaking.

       | 3D guassian splatting might supplant polygonal 3D for many
       | things. At least for 3D scanned scenes it might make sense. For
       | synthetic scenes it might make sense as well. Very interesting
       | technology! I do a lot with drone photogrammetry, I'm keeping an
       | eye on this tech.

         | Yeah, I was thinking of applying this to drone photogrammetry
         | also. Care to share a list of your core software tools?
         | 
         | I haven't done any myself yet, but I'm looking to do some
         | ASAP... both drone and non-drone.
