Slashdot Quote:

"...describes a new type of imaging technique that finds depth discontinuities in real-world scenes (http://www.photo.net/learn/technology/mflash/merl-non-photo.html) with multiple flashes added to ordinary digital cameras. As depth discontinuities correspond to real 3D object boundaries, the resulting images look like line drawings."

I may be imagining things, but I seem to remember someone doing a similar technique with a scanner and a coin, and extracting normal maps from the resulting images. Might be an interesting way of getting normal maps from shallow 3D real world objects.

Hey Steve, I think you are right. It sure looks similar to this photography technique to get normal maps: http://www.zarria.net/

Hi,

that's kind of it, but I remember someone doing this ages ago on the Max forum, can't remember who it was.

It will be interesting to compare results of doing it with that camera with 4 flashes and the torch technique.

I could see lots of games companies buying these if it works well for capturing real world normal maps.
