I feel exactly like Randy when it comes to Syntheyes which I own and use, and PFTrack which I used to own and use, but ditched em cause the company sucks. I rarely use 3DE, but I love it. I used it right out of beta to track something that couldn’t have been tracked at all back in 97. Its my choice, but it’s a little bit more money than I’m down with puttin out, when usually I just need a camera and maybe some GEO. It is super legit software and Wolf the guy who created it is/was ( I don’t know him anymore ) a super legit human. Maybe when my Syntheyes comes due, I’ll switch back to 3DE.
