Wicked cool: Building a 3D model from video
Here’s something pretty well guaranteed to put a smile on your face, I think: the Australian Centre for Visual Technologies has developed VideoTrace, "a system for interactively generating realistic 3D models of objects from video." A user sketches a few surfaces, after which the system works to generate 3D data. The short video demonstration is a little ho-hum until near the middle, which is where the uncontested smiling begins. ;-) [Via]
This demo makes me think of Strata’s Foto 3D, a tool for generating 3D models from within Photoshop, using just a series of photographs. By placing an object onto a specially printed piece of paper, then shooting it from a variety of angles, you give the software enough info to generate a 3D model that can then live as a 3D layer in Photoshop CS3 Extended.
It also reminds me of Extended’s ability to set 3D planes on a photograph using its Vanishing Point plug-in, then export the results as 3D data for use in After Effects and other tools. With it you can export an image like this as 3D data, then set camera movement in AE and create an animation like this.
