Hi Eric

Ive been using agisoft for many vfx projects and experiments such as performance capture.

The way i have been getting data is to setup 2 (somtimes 3) cameras (in my case a 7d and a 550d) at 30-40 degrees apart in front of my face and film a sequence/performance.
I then line up these scenes/sync and render out frame sequences.
Ive then batched these through photoscan and the resulting meshes saved out in sequence.

Ive then used 'supermesher' from Boomler labs to create a cache/pointcache file from the obj sequence.
You then render a depth render/pass from this performance and the resulting depth map can be used to drive a dense grid (non changing topology) - which in turn can have constraints and skin wrap added to it - which would drive another mesh...such as a character mesh or rig.

Ive doen this a few times. Il see if i can dig it all otu and make a video to put up on vimeo

cheers

Face and Body Scanning / Re: Our Results Thus Far

Pretty interesting. The makeup certainly yelds good results and helps alignment.
I havnt had too much trouble gathering head/face data from people holding as still as possible or even laying down.
Interestnig to see you used greenscreen/flat background for your subjects - i didnt think this was advised? i wasnt able to get as good results when i shot against a uniform background.

Im using a 550d and 7D with calibrated lense info. A higher end DSLR and even lighting are certainly the key to good mesh generation.

Hi there,

Just started to play with photoscan recently and bought a license earlier on.
Stunning results from your package - really pleased so far. For VFX purposes - its an invaluble tool - being stable, fast, accurate and mindblowingly easy :)

I made a couple vids from results so far.  Looking forward to future developments
