Thanks slimbuck. Yes, using larger sensors does mean more challenges with DOF, but it also comes with higher-quality images and point clouds for alignment.
I used around f/29, which is quite high and has diffraction, which makes it less sharp overall, but I think it is better than using a wider aperture. There is probably a happy medium.
I used lens tilt to adjust the focus plane, that's when the sensor stays level but the lens tilts up or down.
It's a manual focus lens, so focus stacking would be very tedious. If it were electronic, it could be automatically captured by the camera provided lens breathing isnt an issue.
It's quite a large model, so yes, some LOD settings or optimising is needed for real use.
NIRA.app can be used to stream very large mesh and 3DGS models to low power/data clients, although this is not really 'consumer' focused and more focused on AECO.
