# OpenPBR Surface
Shader Playground, rendered in Arnold for Maya, using OpenPBR Surface. Artwork by Nikie Monteleone.
OpenPBR Surface is a specification of a surface shading model intended as a standard for computer graphics. It aims to provide a material representation capable of accurately modeling the vast majority of CG materials used in practical visual effects and feature animation productions.
OpenPBR Surface is an open standard hosted by the [Academy Software Foundation](https://www.aswf.io/) (ASWF), and is organized as a subproject of [MaterialX](https://materialx.org/).
### Specification
* **[White paper](https://academysoftwarefoundation.github.io/OpenPBR/)**
* **[Parameter reference](https://academysoftwarefoundation.github.io/OpenPBR/#parameterreference)**
* **[Reference implementation](reference/open_pbr_surface.mtlx)** – written in [MaterialX](https://materialx.org/)
* **[BibTeX citation](openpbr.bib)**
### Resources
* [MaterialX Web Viewer](https://academysoftwarefoundation.github.io/MaterialX/?file=Materials/Examples/OpenPbr/open_pbr_default.mtlx) - WebGL rasterization renderer using MaterialX [implementation](reference/open_pbr_surface.mtlx) of OpenPBR
