    I'm trying to stitch together a few dozen photos I took of a building into a navigable 3D model.

    I've tried several times to use Agisoft Photoscan, but it's a terrible piece of software, and I can't seem to translate the instructions in a meaningful way. Sure, they're in English, but they are just awful. My 3D files are messy, take forever (4-6 hours) to render, and I can't seem to find a way to nicely export them into any other software for viewing (like After Effects, etc.).

    I know a few folks are high on Pix4D but it's Windows 64-bit only, and won't run under Parallels. I don't have a machine that can run it.

    I've tried MS Photosynth, but it doesn't seem to work, either.

    And I've tried using Autodesk 123D Catch, but it seems as though it is now a dead product. Won't work at all.

    Is there something I'm missing out there? Obviously I'd like to see something that works before I invest money in it. So far I've seen nothing that has impressed me, and I'm really easy to impress.

    Your comments? Thank you!
    Steve

    Just discovered Autodesk ReCap 360 and am trying that.

    Thanks, Dave, but that one's 64-bit Windows only, too. Doesn't look like the 32-bit version is as capable.

    Anybody else?

    Here's a version with Autodesk ReCap 360.
    This was done with a GoPro HD Hero3+ Black edition with 4K stills de-fished with Lightroom.
    I used 45 or so photos from various angles.
    To be honest, I'm very disappointed with the quality.
    I'd be curious if somebody has Pix4D and would be willing to run this set of photos through it for me. I've attached a couple of the photos and I'm pretty sure these were done the right way.

    That is disappointing, isn't it.

    Steve if the price was 'free' then not bad. Supports the theory that the value of something that is free is pretty close, maybe not quite zero. Easy to understand why the real good stuff charges so much money as posted elsewhere.

    I agree.

    But I did buy Photoscan from Agisoft, and it's not much better. And Photoscan takes about 10 hours to completely render this scene. And there's no obvious way I've figured out to be able to share Photoscan's output.

    I realize this is a little old but if you still care I have a copy of pix4d that I wanted to try out. I'd be happy to run them thru and compare results if u want to post them on a hosting site or whatever, I'll try to pay attention to how much time it takes to render on my machine....the tut says hardware acceleration helps so I'll give it a go.

    Thank you, Jake.
    I am about to re-do this test with my 5D and a Canon-compatible GPS recorder to see if geotagging the photos helps at all.

    l[/quote]Steve what GPS recorder are you using? I am trying to find one that's compatible with the Mark II.

    I'm using this one: http://amzn.com/B00M04MGOM
    Doesn't say if it's compatible with the Mark II. Might not be.

    One of the questions asked and answered:

    Question: doesn't not work on 5d mark2...!!!!!!!
    Answer: I can't answer for the 5dmark2 but I can answer for the 70D: Unfortunately it didn't work at all. There were no real directions and I guess I got what I paid for and I returned it. . I bought the Canon GPS and it works perfectly.
