Paul Debevec: cutting edge research
Paul Debevec's research has been at the core of many key CG
lighting innovations which have driven and still drive the large
majority of high end feature production now adays: HDRI, Median Cut
algorithms and the aquisition of facial reflectance, to name a few.
Paul Debevec's collection of papers can be found here.
A practical conversion of Paul's research can also be found in the collection of tools that Marc
Mehl and
Christian Bloch have released to the public through their
Picturenaut toolset.
Here is a direct link to the Picturenaut's page.
Make sure to install the software as well as the collection of plugins it comes with.
You can download a copy of the software and plugins from here as well.
