Khronos glTF Extensions Make 3D Assets More Realistic Than Ever

glTF LogoKhronos® announces the ratification of the latest Physically Based Rendering (PBR) material extensions for glTF™. This latest set of PBR extensions for glTF will allow developers and artists to create more photorealistic 3D graphics that can be deployed on web browsers, mobile browsers and apps, and more.

The three new extensions build on the existing support for PBR in the glTF 2.0 format by adding refraction, specular, and volume-based lighting. These extensions allow a wider range of products and objects to be represented realistically as 3D assets:  

  • KHR_materials_ior: The Index of Refraction describes the way that light is scattered as it passes through a material. By enabling artists to set different IOR values, a diverse range of materials can be made to look more realistic, including air, water, eyes, glass, sapphire and diamond.
  • KHR_materials_specular: Specular properties are an object’s mirror-like properties: its ability to reflect light regularly, creating coherent reflections of other objects. The specular extension adds two parameters to the metallic-roughness material: specular and specularColor. Specular allows users to configure the strength of the specular reflection, and specularColor which allows artists to use effects known from the specular-glossiness material. This extension allows artists to design more beautifully lit virtual photoshoots of products.
  • KHR_materials_volume: The volumes extension enables mesh surfaces to act as an interface between volumes and to enable more realistic refraction and absorption properties to be seen in transparent materials. This extension gives translucent materials the appearance of depth and heft.

Enabling Consistent and Powerful Asset Product Metadata for 3D Commerce

3D Commerce LogoAs the number of 3D assets used in e-commerce rapidly increases, the need to embed semantic information describing virtual products within real-time 3D formats such as glTF becomes ever more urgent. 3D asset files that contain descriptive and administrative metadata such as product descriptions, details on intellectual property rights, creation and modification dates and other detailed authoring history - all in multiple languages - will enable the management of 3D virtual product catalogs, and the sharing of assets between vendors, retailers and end user platforms at industrial scale.

To address this, Khronos announced the release of the provisional KHR_xmp_json_ld glTF extension to add full compliance to JSON-LD, replacing the original KHR_xmp extension. Support for JSON-LD serialization significantly increases the power and flexibility of the extension, making it a perfect vessel to carry information about products within the 3D commerce ecosystem. You can use the KHR_xmp_json_ld extension today, and Khronos is seeking community feedback on the provisional specification before finalization. If you have feedback please submit an issue, here.
