BRDF material generation for PBR (pro version
« on: September 11, 2015, 07:29:07 PM »
Next stage in Photoscans evolution?

Use HDR surface capture to provide the BRDF (material reflectance properties reconstruction) data for physically based rendering.
 i.e. Quixel’s Megascans http://www.quixel.se/dev/megascans is an example of such a library of scanned data.

.. this method/paper below would only need a single extra photograph to have all the data to work? (A photo of mirror sphere (or 360 pano) a paired to a solved photo's position giving light direction) ...all the other methods i can find would need multiple lights with polarisers on the lights.

Have Agisoft tested these possibilities yet, and why it might not work?
