123D Catch - AutoDesk? Did something right? And for free? Confirm plz.
show user profile  LionDebt

Use mobile phone camera, take a hundered (or so) pictures of subject, voila 3D scan?

Going to try this out when I get home. Thought I'd share.

It's a ploy.

... Gateway 3D... Before you know it you own a license to 3DS.

I've used it quite a few times. It can work, or it can go horribly wrong. It doesn't do the processing on your device/computer, it sends the pictures off to Autodesk then you await a 3D file in return.

If I could remember my password, I'd link to some of the models I did a while ago when it was in beta.

Yeah. There are other free open source ways to compute it on your PC. Google open source photogrammetry.

Here is a technique I have used myself that seems to work pretty well.

It's not a gimmick man. There are lots of practical uses. Like this...

and the stuff Reeves posted recently with the old woman, that was scanned using similar technology I think, granted with a large array of cameras though.

And bolts was talking about hdr mapped environments instead of light probes. I remember reading about some movie that was scanning all the sets like that.

I think it`s prob most useful for single objects particularly organic stuff as opposed to whole scenes. Here`s one of the coolest practical examples i`ve seen of it ( back when it was called Photofly ), the videos are definitely worth watching:!&s=b1893b709ba36370af7ccbda6efd3e7b

I think initially the texture output etc were higher res and then they started bottlenecking it a bit when it got really popular. Would be interesting to look into some of those alternate versions BishBash posted..

[edit] The Bits of Bread scene is a really cool example, nice one.

Oh, i didnt mean the technique, its awesome but the app from autodesk looks a bit like a gimmick to me.
Have you checked this stuff? They capture footage and convert it to 3d animated models using camera.

Wasn't someone on this forum working on some turntable + webcam thing that did 3d scans? Or am I going crazy?

@Dave - br0t was. And has released / developed it now - if memory serves - through KickStarter.

Okay, so having had a little play around with it now... The app is terrible (or combination of iPhone camera + App). It's been "uploading" and then "processing" my photos for the best part of 3 hours now, and it seems stuck on the very helpful stage of "Thinking some more".

You're limited only to matte objects. No shiny / translucent / reflective objects - this includes anything in the frame (not just the subject).

Any featureless or plain objects (such as walls) - you'll need to apply coloured tape to or some other recogniseable point of reference for the algorithm...

Over/Under exposure breaks the algorithm also - so again, you're mostly limited to shooting outdoors in good conditions or in well lit interiors.

Meh, all feels quite gimmicky at this stage. But could be promising in the future. Most likely with an AutoDe$k price tag.

It seems that they've rebranded PhotoFly into 123D Catch and severely bottlenecked a lot of it's features (as ScotlandDave said).

Ah gotcha. :) Bertrand seems to get good results though.

I just wanna scan shit with a kinect, not take photos in a circle.

Almost ordered a used xbox one kinect for 80 dollars until I realized that MS makes one that specifically works for PC (the rest don't) and is charging +$200 selling the SDK separately (or some shiz like that).

Not sure the resolution of the new kinect but the old one was vga afaik ( ie 640x480 ) so not really great tbh - just saying!

Yeah it was low res but you can pick it up and use it as a scanner. The new one is better too! :)

I'm just impressed with the depth.
