Better? A turn on the spot shows a wreck everywhere but forward.

Those are the areas that are occluded in the input images. If you look at the bushes, you can see that the front is clean while the back is a mess. Probably the starting position could be chosen a bit better.

The path to left and right is occluded? By what?

By not taking photos of it... what else? The data wasn't there, so it couldn't be generated

Actually, this might be a lack of understanding, look up what gaussian splatting is.

That's not occlusion.

lol, there can be more than one explanation, you're being purposely obtuse.

Occlusion can block you from taking a photo.

Not taking a photo can block you from taking a photo.

Sometimes, there are two things that happen!

Seriously, you'd understand if you actually bothered to look up what Gaussian Splatting is

This raises the question, do any of these projects have workflows for combining images taken from different positions? Or does that just work out of the box? (I have no machines atm with anything better than 10yo eGPUs ;~<)

Yes the whole field could more or less be described as combining images taken from different positions :)

As I understand the typical workflow starts with a stack of frames which have a small offset in position /orientation which the model is able to derive due to sufficient similarities to the adjacent frames; if I created three stacks like that which are internally self-similar but were taken from three viewpoints 20 meters apart, so perhaps only a small portion of the scene is common between them, could the model still orient them into a single scene? I suppose you could just capture the "transition" frames as you move your camera from one viewpoint to the next as well and then it would be treated as a single path?

The article includes a visualization of the different positions that images were taken from: https://pxl-th.github.io/video/camera-frustum.mp4 It's just that they're all bunched around the statue and the starting position for the rendering is a bit farther away, where there's direct line of sight to spots not covered by those images.

do you know how gaussian splatting works?
