Khronos PBR Neutral Tone Mapper Released for True-to-Life Color Rendering of 3D Products
The Khronos Group has released the Khronos PBR Neutral Tone Mapper specification and sample implementation. Khronos PBR Neutral is specifically designed to display 3D assets rendered using physically-based rendering (PBR) with true-to-life colors that are vital in applications such as eCommerce, architecture and CAD. The Khronos PBR Neutral Tone Mapper is already enjoying wide adoption and support by 3D tools and engines including <model-viewer>, Autodesk, Babylon.js, Blender, Dassault, Filament, London Dynamics, Phasmatic, Three.js, and Threekit.
Inside the Evolution of glTF: Microsoft & Babylon.js Collaboration with the Khronos Group
Gary Hsu from Microsoft recounts Microsoft's history of involvement in the 3D Formats Working Group and its work on the glTF file format. Gary details his group's early work in PBR, helping define glTF 2.0, their participation in the Khronos Working Group meetings, Face to Faces and conferences, and their present involvement.
glTF Webinar - Tuesday, September 19th
Unleashing Creativity in 3D Models with glTF and PBR - Join us for this webinar presented by Eric Chadwick to exploring the artistic frontier of using The Khronos Group glTF 3D assets. The webinar takes place at 9am PST on Tuesday, September 19, 2023. The artistic creation of realistic materials in real-time 3D models in glTF using physically-based rendering (PBR) is discussed and demonstrated. Attendees will gain valuable insights into the best practices, workflows, and optimizations required to simulate iridescent, anisotropy, and other effects and to achieve stunning visual realism for 3D assets. Eric will discuss the techniques used and available tools to achieve them, with plenty of time for Q&A. For additional info and to register visit:
Khronos Launches ANARI 1.0 as the Industry’s First Cross-Platform 3D Rendering Engine Open Standard API
The Khronos Group announces that the ANARI 1.0 open standard, cross-platform 3D rendering engine API, has been finalized and that multiple implementations are shipping from AMD, Intel, and NVIDIA, together with an open-source software development kit (SDK) from Khronos. ANARI significantly simplifies the development of applications in domains such as scientific visualization by providing high-level functionality to build an in-memory scene representation to be rendered without the need for low-level graphics code and enabling the use of any 3D rendering engine that supports the ANARI API. The ANARI 1.0 specification has been openly developed and incorporates significant community feedback, including compatibility with glTF Physically-Based Rendering (PBR) materials. ANARI has already been widely integrated into scientific visualization applications and is expected to be used by diverse applications needing portable access to multiple rendering engines delivering sophisticated 3D functionality such as ray tracing and global illumination.
glTF Validator and glTF Tools for VSCode updated for new PBR Extensions
Lots of exciting glTF news today! Khronos announced three new new Physically Based Rendering extensions for Clear Coat, Transmission and Sheen which continues to build a powerful, interoperable, material model for the glTF ecosystem. As well, new versions of glTF Validator (2.0.0-dev.3.3) and glTF Tools for VSCode (2.3.2) were also published today, adding support for all three of the PBR extensions.
