COLMAP + CloudCompare with a good CUDA GPU (more VRAM is better) card will give reasonable results for large textured objects like buildings. Glass/Water/Mirror/Gloss will need coated to scan, dry spray on Dr.scholls foot deodorant seems to work fine for our object scans.

There are now more advanced options than Gaussian splatting, and these can achieve normal playback speeds rather than hours of filtering. I'll drop a citation if I recall the recent paper and example code. However, note this style of 3D scene recovery tends to be heavily 3D location dependent.

Best of luck, =3
