View Full Version : 3D from photos
01-17-2009, 01:10 PM
Hi, I just wanted to post a bit of info on a web based image based modelling app that I have started playing around with. (I may be of use to some folks out there)
Basically it will convert your photos into a 3D relief. You will need to set up an account- log onto the web site and then submit a series of photos, which the app then uses to generate the 3D surface- (I suggest minimum of 8 or so in focus shots of your surface – moving your camera parallel to the surface during your shoot).
Once you have uploaded your images- you can crop the section o f the photo you require - through the site, once that's done the site will then email you (when the images have been processed ) to come and collect your 3D mesh- The site has a cool 3D preview function, which allows you to scale preview your 3d model( you will need java installed browser), and a gallery of previous photos and resulting 3D models created by the app.
The web based version of the app only supports relief style 3D surfaces – but as I understand it the commercial app will support full 3D turn around mesh creation without any of the usual fiddling with reference point/calibration that is usually involved with image based modelling.
Note there is also .ply to collada converter on the web-site, go to http://3dsee.net/faq/view/4/23 to download the file (it only works for windows).
I’m working on some pointers on getting out the best out of your shoot and ways of integrating the high poly mesh data spat out and ready for editing and re-use within Zbrush/Maya/.

The need to take ABSOLUTELY aligned photos may be a limiting factor.
All three of my attempts only returned an unspecified error.
We discovered something incorrect with your images and we couldn't convert them.
Please click here for an explaination of the error from the FAQ.
when I "click here" I get
Sorry we could not find the FAQ you were looking for please contact the administrator.
They will need to do a better job of explaining the errors so users can correct their work.

nine hours after I got the error messages above, I get e mails saying two of my three attempts had been converted.
The PLY seems to be a variant unknown to my 3D software so examining that was out.
The bump map is just a lo-res 8-bit preview so that was of limited use, also. Pretty jaggy stuff.
I will look forward to them refining their process, and will look forward t more detailed results.

Yep it seems the site is early days (as well as the FAQ).
How many images did you post - with my stuff I have been taking at least 8 photos using the consecutive images switch on my digital camera (the kid capture settting). The images dont need to be perfectly alligned as far I can figure - but do need to be in focus.
I convert the .ply format into the collada fomat (*.dae)
Using the drag and drop app from thier site.
Collada data imports into maya fine - but you will need to download a plug for your app (It will bring in the vertex colour data) For a Maya or 3DSMax version go here:
Whats your main 3D app?

I get the felling that they're "Server" is a bunch of automation scripts running images through CrazyBump. Definitely a wait and see situation for me.
