> recreating a 3d view using multiple photos from different angles I've been waiting for that for years. Searched for it a few months ago, still nothing.

Er, http://photosynth.net/

This is for panoramas, not 3d objects right? I meant merging photos of an object from different angles.

Edit: It's not even working. Photographed something from different angles, synth it, and it appears on their website as a slideshow. Like a normal jquery slideshow except you need Silverlight®.

The videos don't load for me (due to mixed content, I believe), so here they are: https://www.youtube.com/watch?v=SOpwHaQnRSY https://www.youtube.com/watch?v=sA4Za3Hv6ng The hyperlapse of the climbing video looks like an FPS game from a decade ago with texture refreshing as you get closer.

Hmm... Did I not embed these correctly? The project page as well as the embed links are plain http:// this is what it should be, no?

since the page is also available via https, using protocol relative urls for the embeds should fix the issue (src="//www.youtube.com/embed/SOpwHaQnRSY" instead of src="http://www.youtube.com/embed/SOpwHaQnRSY")

Hi spindritf -- I work for YouTube and have been looking into some mixed content issues with embeds. Mind if I email you and ask for some details about this scenario?

Barrym is probably right: HTTPS everywhere forces ssl for the site, but not for the embedded videos. Feel free to shoot me an e-mail though, no need to ask.

I'm not sure why the site isn't working, but the software is definitely for 3D objects, not just panoramas. Maybe your photos didn't have enough in common for it to work?

Personally I thought the climbing video was breathtaking. With a decent film crew it could be an absolutely breathtaking scene in a climbing film.

There was a mildly annoying effect somewhat reminiscent to pop-in seen when terrain geometries go from lower to higher detail in video games. It was particularly evident here: https://www.youtube.com/watch?v=SOpwHaQnRSY#t=170 It would, I think, be even more distracting if the video was higher resolution.

Yeah, I noticed that too. I wonder how much of that is really an artifact of the lighting and (relatively) low resolution of the camera. Something shot with a better camera and lighting that reveals more terrain might give the algorithms something better to latch onto so the terrain models more cleanly.

GoPros can shoot in 4K, they're not a low resolution camera by any means.
