This is a model of a sandstone boulder from my backyard made using Agisoft Photoscan. Use it any way you see fit, but please let me know if you find it useful. Enjoy!
I doubt it would work with only two photos. PhotoScan works better with photos with lots of overlap. Many photos taken from all around the object. To do a live person, you would need some sort of multi-camera rig so that you could take all those photos at the same time. People move too much to get really good results taking one photo at a time. That's why rocks are so nice!
If you are really interested in scanning a person, there are examples of scanning rigs that have been built to do the job. Just Google. I think there are some examples on the PhotoScan website.
Good luck, and have fun.
Question, can you make a 3d model of a person using PhotoScan with only front and side photos?
