OpenPBR - a Proposed Industry Standard Physically Based Shading Model

Video on demand

OpenPBR is a shading model that is meant for interchange of surface appearance in computer graphics. Having an established shared shading model that is well defined and well understood, and that can be implemented on anything from a cellphone (albeit for simplified display) to a high-end rendering engine for feature film production is very valuable. The model should also help users make physically correct and beautiful renderings. Previous attempts in this arena have either been too simple to work for true feature-film quality effects, or had too many complex parameters to easily allow the user to make nonsensical or nonphysical results. 

The OpenPBR project started as Adobe and Autodesk realized they each had models that were almost - but not completely - identical. After several meetings between the two companies trying to iron out the a single joint standard, the effort caught the interest of ASWF (Academy Software Foundation), and is now a project under the ASWF umbrella, and it is complementary sister-project to other ASWF projects like OSL (Open Shading Language) and a sub-project of MaterialX.

Zap Andersson is a software engineer at Autodesk, working from his home office in the Swedish countryside with rendering in 3ds Max and Arnold, shader development, integration of OSL, and many other facets of rendering but with a particular expertise in shading and shader writer, being the author of all of the 150+ OSL shaders shippine with 3ds Max.

Zap has a previous life at NVidia, through the acquisition of mental images - the makers of mental ray - where Zap worked many years with the official title of "Shader WIzard" (yes, really!) where he developed things like the fast subsurface scattering, the production shader linbrary, and the mental ray architectural material.

When not being a pixel whisperer and shader nerd, Zap spends time with his family and his two cats, Rufus & Gizmo, and when darkness falls, live-streams strange improvised electronic music on a tower of vintage analog synthesizers over on his "zaptronic" youtube channel and on Twitch.
