Scientists Work Out Way to Capture 3D Texture Info in a Flash [Textures]
Gizmodo —
Some scientists at University of Manchester in the UK and Dolby Canada in Vancouver have worked out a way to capture 3D info of complex-textured objects really simply with a camera flash. You should care about this because it's likely to make the textures applied to characters and objects in computer games way more realistic: normally texture capturing needs expensive devices like laser scanners. Instead this technique uses something a bit like high dynamic-range photography, with two photos taken of a real-life texture: one with flash, one without. After some nifty image processing later, working out where the ...
Capturing 3D surfaces with a flash camera

Capturing 3D surfaces with a flash camera via /.
Comparing a flashlit photo with one taken in ambient light can reveal the texture of a surface, and could help develop more realistic computer games... The virtual worlds in computer games provide a realistic backdrop to the action. But step too close and the effect is lost – you'll see that textures and patterns are usually displayed on flat surfaces that look dull and artificial.
A simpler way to add depth to textured surfaces could change that.
The new technique can reconstruct the depth of a surface simply by ...
New, easier technique for capturing high-res textures
CrunchGear —
I’m no asset creation specialist, but from what I’ve heard it’s not that difficult to get textures, although making a decent normal map that actually corresponds to a texture’s source is tricky. Some boffins at Dolby thought there had to be an easier way than what was available, so ...
