More fascinating 3D face bits

Wow–Friday’s face-finds were pretty cool, but this technology takes things in a whole new direction.  Volker Blanz and his collaborators have analyzed hundreds of human faces, then built a representative mesh that can be adjusted along various axes (male to female, young to old, gaunt to fleshy, etc.).  The model can then be mapped to a photo in order to reshape a face (e.g. open a mouth, add a smile), change its orientation in space, or even replace it altogether.  This
5-minute video is well worth a watch, and you can find additional bits on Volker’s site.  I can imagine tons of potential applications.  [Via Gregg Wilensky]

Speaking of mixing 2D & 3D, at Macworld Google demoed a new version of SketchUp, the simple-to-use 3D package they acquired last year.  It features tools that in some ways resemble Photoshop’s Vanishing Point, allowing users to attach planes & other shapes to a photo, then generate 3D artwork; check out this demo video.  (Careful: On #3 the demo artist’s frenetic zooming is a little nausea-inducing. ;-)) Whereas VP is geared towards painting/cloning/healing in perspective, SketchUp is geared toward building full 3D models.  Nifty stuff.  [Via]

    Very interesting stuff, John!
    While I was reading this post, I couldn’t help thinking that this is like an easy-to-use variation of camera mapping for everyone. As you surely know, Camera Mapping (or camera projection) is a techique film fx people have been using for years: it’s about navigating a 3D scene that is constructed from a background picture or matte painting. But it’s much, much harder to do than what I saw in the Sketch Up video :)
    I always find it very interesting when something that’s been around in high-end environments becomes easy to use and affordable in every sense for anybody to use.
    All the best,
    [Oh yes–commodification of what was previously rare/expensive/esoteric is a good & natural process. Of course, it keeps us on our toes as other people add healing, Shadow/Hightlight, etc.–as well it should! –J.]

    I do like pictures, I alway convert pictures to formats that I want. So I know some software that can help you to convert and print 2D and 3D model images,that is, CtrlView
    – CtrlView helps you view, convert and print 2D and 3D model images, you can rotate, zoom in, zoom out and adjust color to your 3D objects, and then save it into Macromedia Flash for your website.
