Why do you think it matters with such a rate of simplification? Are you talking about sub-pixel accuracy of individual vertices or overall geometry? Do you have examples?
Doesn’t it depend on what you are trying to do and how you want to achieve it? I guess that if you have a fixed set of images that you have to work with (aerial images for example) and then need to squeeze the last bit od detailing out of your material, then high detail is probably the only way to go. If however you want to scan something close range where you can go back and take more images if you need, I think that is also a possibility and doesn’t necessarily require high detail calculation. I have tried that on occasion and the result in my cases was that high detail spews out WAY too many points for my needs and also takes WAY too long. Normal Detail is also pushing it sometimes in my opinion. My examples are architectural features of medieval buildings, e.g a base of 50 cm diameter and I don’t even have to fill the whole image (10 mp) with it to get results that are good enough to be able to measure the moulding accurately.
But I am keen to learn more!
