| Amazing , great work !

| 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

| 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

| N1ckFG wrote:
| 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.

| This was... an A-ha moment (if you know what I mean).

| 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.
| DiddlyWinks wrote:
| 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.
