Digital Emily on github

The Digital Emily project from the USC ICT and the Wikihuman Project provides texture maps, geometry and reference photography for a model scanned in the Light Stage.

For this project, a github repository has been created with Maya assets ready for use in matching the real Emily with different renderers. The data set currently includes example images and materials rendered using mental ray and PBRT v3. These were created with an eye towards facilitating further experimentation with the existing dataset, extending material definitions for Vray and the skin shader in OSL provided on the main site.

The repository can be found here: Digital Emily.

A direct download of the assets and scenes is available here.

The Academy Color Encoding System 1.0 (ACES) was launched in December 2014 by the Academy of Motion Picture Arts and Sciences. The result of over 10 years of industry-driven development and testing, ACES provides a standardized color management infrastructure to replace what was lost in the transition away from film. A key application addressed by ACES 1.0 is visual effects production. The addition of the ACEScg color encoding to compositing, lighting, rendering and other CG workflows will simplify element interchange and preview, as well as enable high dynamic range and wide gamut deliverables.
