3D Tiles enables sharing, visualizing, fusing, and interacting with massive heterogenous 3D geospatial content across desktop, web, mobile, and metaverse applications.
The Open Geospatial Consortium (OGC) seeks public comment on a proposed update to the 3D Tiles Community Standard, which is used for sharing, visualizing, fusing, and interacting with massive heterogenous 3D geospatial content across desktop, web, mobile – and now metaverse – applications. Comments are due by 25 May, 2022.
The proposed v1.1 revision to the 3D Tiles Community Standard, planned for submission to OGC by Cesium, is designed for streaming high-resolution, semantically-rich 3D geospatial data to the metaverse. 3D Tiles 1.1 promotes several 3D Tiles 1.0 extensions to ‘core’ and introduces new glTF™ extensions for fine-grained metadata storage.
The primary enhancements proposed for OGC 3D Tiles 1.1 include:
- Semantic metadata at multiple granularities
- Implicit tiling for improved analytics and random access to tiles
- Multiple contents per tile to support layering and content groupings
- Direct references to glTF™ content for better integration with the glTF™ ecosystem
3D Tiles 1.1 is backwards compatible with 3D Tiles 1.0 – aside from version number itself, valid 1.0 tilesets are also valid 1.1 tilesets.
3D Tiles 1.1 is expected to be finalized by Cesium in May, 2022 and subsequently submitted to OGC for consideration as a revision to the existing Community Standard. Reference implementers are committed to updating their implementations with the final release of the specification.
3D Tiles was first announced at SIGGRAPH in 2015, and was published as an OGC community standard in 2019. Since then, the community has built apps, exporters, APIs, and engines with 3D Tiles to grow an open and interoperable 3D geospatial ecosystem. This collective experience building with 3D Tiles, combined with the continued growth of 3D geospatial data availability, especially semantic metadata, and increasing user interest in digital twins and the metaverse, has led to this revision of the 3D Tiles specification.
A Community Standard is an official standard of OGC that is developed and maintained external to the OGC. The originator of the standard brings to OGC a “snapshot” of their work that is then endorsed by OGC membership as a stable, widely implemented standard that becomes part of the OGC Standards Baseline.
The 3D Tiles v1.1 Community Standard Justification document, which details the changes in v1.1, is available for review and comment on the OGC Portal. Comments are due by 25 May, 2022, and should be submitted via the method outlined on the Proposed v1.1 update to 3D Tiles Community Standard public comment request page.
About OGC
