So I tried out AD's 123D Catch this weekend. Interesting, kinda wonky, and the model needs some cleanup.

This wireframe was created using the lowest of their 3 resolution options. The poly flow is not awesome at all and on the middle res setting the model still needed cleanup but was more of a pain because of the higher poly count and horrid flow. With some cleanup and a decent normal map this would prolly work. The thing I hate about the program is that you HAVE to use the cloud. For the time it takes to upload photos and have their cloud process, I'm pretty sure my computer could have already processed it.

All in all I think there is some merit to this technology, like creating assets from a real location for archvis work, and not wanting to spend tons of time on these assets because they're important but not the focus.

I'll do another test or two and play with it some more but I'm hesitant to rely on it because it's AD, it's cloud, beta and free so it could go away instantly.

Still pretty cool indeed, and poly flow fixes could be done in 3DCoat or Zbrush quickly I guess?

Try it with Meshmixer (not sure what will happen to the textures) ..

Not sure, I have neither. I have Sculptris but I've only launched it a couple of times and I think it wants a watertight model? I wasn't able to pull the eagle into Sculptris yet.

Is that what they're calling Photofly now? I tried Photofly a few times and had mixed results, none were really fantastic. They all required a lot of work on my part, even after loading the pictures in.

Yup, same program. I think it's something that can be OK depending on what you need. My first test was a complete flop. For the eagle sculpture I used my good camera and took about 50 photos. Supposedly it doesn't do well with shiny/reflective and transparent objects, which makes sense.

Yeah I tried doing my car and it was just an awful mess due to the reflections. Maybe I should do it quickly on a day when my car is all covered in frost.

The Catch program is intriguing. I've looked at desktop software before and it was pretty costly (for example, Strata's Foto 3D costs about $700) and clunky. Worth a try!

Ooops, I guess you still need a desktop component. And there isn't a Mac version (foiled again!).

I don't know if this would meet your needs, but Ten24 has a blog post about 3D Scanning on a Budget (http://www.ten24.info/index.php/3d-scanning-on-a-budget/). The program they reviewed, Agisoft PhotoScan has a Mac version.

That tutorial isn't exactly under $200 if it requires one to buy zbrush to follow it.

Further testing. It seems that 123D Catch doesn't like solid background surfaces, like the sky. It can't distinguish what's sky vs. what is the object.

Coincidence, I was just looking at this program today and I can see why I'd use it. In my case if I want to make something like a car model I have to rely on blue prints and reference photos. You are never 100% sure if the end result is proportionately true to life.

Now, I can take a bunch of photos of the car and generate a mesh, load that mesh into a background layer and use it to get my model to line up to the real proportions of the car. I'm going to scout the next car I want to make, take a ton of pictures and try this out.

But it could be anything, products, people, just use as a background reference for accurate proportions.

It's free, can't complain about it.

Philbert

It does not work for cars. I tried to do mine and the reflection completely screws it up.

Edit: Oh, sorry just for proportions. That might work.

I took some photos today of a Volkswagen, it's an older model to the one I have previously modeled but I thought it was an opportunity to test out the idea of using 123D to make background reference models, and also to see how close I came to getting the proportions right.

I didn't get a perfect replication from my photos but I got enough to make a reasonable 3D shape to load into modeler and compare how my wireframe matched up.

I was pretty happy to find that my mesh matched all the major parts of the 123D version. So as a proportional modeling guide I think it shows promise, but I have to learn how to take better pictures to get a good result. I rushed that part because I was looking out for traffic, you would want to get the vehicle and park it somewhere like an empty car park and take your time with the picture taking.

That looks pretty similar to the results I got with my car. Mine was parked in my driveway.

I think you need equal space and distance around the the car, at least for the back, side and front, you probably don't need to have both sides, but the problem with cars on the street is that there'll be another car parked next to it so you can't get equal distance all the way around it. I'll do a test with something of similar size to a car that is less obstructed to see if the result is cleaner, or I might go park my car somewhere where I can do a total 360 degree revolve at equal distance.

Be careful too, some people may not be happy if they see you taking pics of their car without permission.

I owned that car as a young man in the 80s It's a 1973 vw.

It had 5 mayor flaws. It was noisy, slow, ugly, unconfortable and indestructible.

I'm kidding I had a ton of fun with it, put some huge tires on it and went off road with it a lot.

Nice! That workflow seems to work really well.

I started sculpting one of the lions. I haven't worked on it in a bit as I started working again (yay!) and I found that my GTX 260 has about a 400k poly limit with Sculptris before it starts to lag. I'm looking at upgrading my card before I continue with any sculpting.

Tried 3D-Coat? The Cuda support might be helpful there, I was able to work on 20 million or more without trouble on my old GeForce 8800 GTS.

I hadn't but I'll take a gander. Sculptris was a 'hey what's this sculpting thing all about' deal.

well I have to say that we used it a few times and the test we did was really quick: we went outside and grabbed a rock and put it over a trash bin. I stood between the bin and the sunlight to create a shade for the rock and one of my mates took pictures of the rock, about 30 pics. in 10 minutes we had the most perfect 3d rock in the world. Amazing!
Then we decided to use it for a real project, and we took tripods, lights etc to photograph some arqueological artefacts...they took photos every 45 degrees and used the lights to create some contrast in the objects...I have to say that it went like crap. 123d couldn't do anything with those photos...
so if you have to take pictures of some object choose a cloudy day and they pictures that cover about 60 or 70% of the previous photo and it will be fine. You guys already know...no reflections, transparencies, etc.
cheers

it might be possible to use a video camera too, film it, then bring it to After Effects and output every X frames...

David laser scanner works well but it's expensive and a real PITA to use.

Here's a really helpful video I found on 123D Catch. It's well produced too.

Well, first you can't just do it anywhere, you have to set up a corner made of two pieces of cardboard taped together with a special grid pattern printed out and glued to them, then of course you're using a webcam so you have to have a good one that's wired and a computer nearby. Next you need a line laser. You can get a laser level from the hardware store for $50 or so but they use a red laser and often have breaks in the line. Neither of which work well with David. So with research you can find a good green line laser that has no breaks in the line. Next sweeping the laser line across the object is very tedious and careful work. Of course you can only scan one side of the model at a time and I don't believe David has any way of merging the scans so that has to be done in something like Meshlab.

myeah, it certainly looks like some extra work... i guess it's best for scanning small parts.
from what i've seen PhotoScan tests are close to as good as laser for headscans, and also provide color info.

I was just trying to use 123D Catch again and it seems that it's broken. It won't connect to the server to upload the photos. I see a lot of other complaints about this on the forum too. One the autodesk people says the problem is only happening to some people. I don't trust them, they also said they were working on an Android version years ago.

PhotoScan is actually quite inexpensive for what it does--the Standard Edition costs $179 and it can work with an ordinary digital still camera. The more expensive Professional version ($3500) is intended for geographic scanning. Personally, I only need to scan things that I can fit into my living room or garage. :)

Yes, I'm comparing the price to 123D, free, and my bank account, almost empty.

Wow a DiVX video! I was just about to uninstall that codec because I couldn't remember the last time I had seen one. Of course it didn't work anyway, keeps saying it's not a DiVX file.
