We present a unified material description and transmission format for real-Time, physically-based shading. Our format is general enough to be used consistently across multiple rendering systems and platforms, covering a wide range of applications from desktop to Web. Furthermore, our format's expressiveness allows to represent a wide variety of real-world materials. First, we define a common parameter set for physically-based shading in modern, real-Time 3D graphics systems. We then demonstrate its applicability for several types of materials on different rendering systems. Finally, we propose a transmission format, in the form of extensions for the glTF and X3D standards.
