Sounds like an interesting project but I’m not tech-savvy enough to know what much of that means lol. However,....I do understand the idea of 3D combined with incredible breasts (which your wife fortunately happens to have) and so I can only say: “Be careful with the 3D feature...it might poke someone’s eye out!”
Have fun and keep posting.

dont forget to break of arms and numb down details to get the time elapsed feel

I did not expect to find such a topic here in this neighborhood, otoh, as you describe your project's goal, nothing can be more classical than a perfect 3D redplica of your wife's breasts (avoiding the t*t word here).
Now my question: What photogrammetry software do you have in mind, there are some apps for iOS and in the Linux world, apart programs developed for the Mac or even Windows.

A more intense communication about that (per PM?) will be appreciated.

Cheers

replica of course!
