Beautiful location and scan! 🤩 Purely drone based photos or some from the ground too?

This one’s drone only cause it was a tricky site to access by foot. But the rest of the Ani scans are a combo

Fantastic!

This is glorious

Stunning, I'll need to check that out in VR.
Curious though, why you didn't train with a sky model. Is there some technical limitation? I think it helpes a lot to ground these landscapes in reality (besides helping with floaters)

btw, the skybox didnt help much here either, even when I had a decent amount of ground photos looking up at the sky.

I'll have to try again when i scan a scene with more of the surround and sky captured intentionally

Hmm, it seems as if the skybox is almost invisible. I had some skybox related issues in Postshot when training with the splat MCMC profile which straight up deleted it, while the ADC profile was usually fine.
Any part of the sky that's not seen by an image would be extrapolated.

Eh, ADC produced just as bad results with less detail on the actual building (sceenshot 1)

however, i think it's better at reconstructing the surrounding (screenshot 2)

heres a better comparison

mcmc (screenshots 1 and 3) vs adc (2 and 4)

surroundings are way more defined with ADC at the expense of detail on the subject scan itself

stim3on.bsky.social•105 days ago

Interesting comparison. How do the splat counts compare between the two versions?
Perhaps you can increase the splat density for ADC to get those details back.

Cause I had so little coverage of the sky! Captured before 3DGS was a thing so many of these scans don’t have much of the surroundings/sky in view
