Khronos Proposes Gaussian Splatting glTF Extension
8.9
Khronos Group this week released a release candidate for a Gaussian splatting extension to the glTF 3D format, inviting feedback from engine developers and creators ahead of formal ratification targeted for Q2 2026. The extension embeds volumetric Gaussian splats directly in glTF files to standardize delivery of photorealistic captures across XR platforms. Major contributors include Autodesk, Bentley Systems, Huawei, Niantic Spatial, and Nvidia.
Key Points
- 1Defines glTF release candidate that stores Gaussian splats directly within glTF files.
- 2Reduces fragmentation and enables cross-platform sharing of photorealistic volumetric captures for XR and web.
- 3Allows developers to integrate splat-based scenes but leaves compression and mobile performance unspecified.
Scoring Rationale
High-impact industry standardization with strong vendor support, but still a release candidate lacking compression and final ratification.
