123D Catch Tips & Tricks

Here’s what we’ve learned from a marathon day at the Met with a full team of artists and museum staff. We want to share as much wisdom with readers as possible, and ask you to please chime in in the comments. Remember, this is a community! If you have experience with any of these technologies, we need to know!

The surest steps to success using 123D Catch to capture and remake art:

Provide enough information with your pictures. Basically, make sure each point in your object is appearing in at least three shots, and make sure there is uniform light around the thing you’re trying to Catch. When you don’t have enough info, you’re likely to get a solid block of mass in your model or a total lack of mass where there should be some stuff. Check out the big hole underneath this ritual seat from the Oceanic Art collection.

– If possible, use objects in the background of what you are trying to capture to help the software parse depth. 123D Catch does not like a blank wall with flat paint.

 

– There is no right way to do this stuff. This is the frontier and we’re figuring this out together. Everyone in this group today was tossing out different ideas and each artist or team of artists was taking a different path toward the goal.

“By taking a whole series of close up pictures just at one level, I got really good 3D detail. Really good reproduction of very, very small depth.” — Michael Curry (skimbal)

“I’m using an iPhone to do this.” — Adam (@adamfont)

    On more tip that took me a while to learn. More isn’t necessarily better. Too many shots produces just as bad of results as too few, but takes much longer to process. I’ve had best success with 25-40 pictures.

    I’m looking to use 123D Catch to capture a 3d model of my dad’s boat, and print him out a model. Anyone have tips for capturing large objects? It’s about 25 feet long, and will be on a trailer. I figure I’ll have my camera and a step ladder. What sort of angle from above would I need to capture the top accurately? And do I need to keep a constant distance?

    I had the best luck “catching” with an iPad 2! :)

    Because the iPad app will only let you take the maximum number of shots (~45-50), and will prompt you ten shots before the end, you don’t get too many. Once “catched” it’s also a seamless process to upload to the 123D Catch servers and preview your catch while planning the next. Of course, to finish the process, you need the Windows app, but the iPad makes catching a breeze!

    Some good tips are in the Autodesk University 2011 123D Catch manual: http://www.thingiverse.com/thing:24915
