3D Tiles

Overview

3D Tiles is designed for streaming and rendering massive 3D geospatial content such as Photogrammetry, 3D Buildings, BIM/CAD, Instanced Features, and Point Clouds. It defines a hierarchical data structure and a set of tile formats which deliver renderable content. 3D Tiles does not define explicit rules for visualization of the content; a client may visualize 3D Tiles data however it sees fit. A 3D Tiles data set, called a tileset, contains any combination of tile formats organized into a spatial data structure. 3D Tiles are declarative, extendable, and applicable to various types of 3D data. The following tile formats have been specified as part of this document:

• Batched 3D Model
• Instanced 3D Model
• Point Cloud
• Composite

This document also describes 3D Tile Styles, a declarative styling specification which may be applied to tilesets. The 3D Tiles specification for tilesets, associated tile formats, and the associated styling specification are open formats that are not dependent on any vendor-specific solution, technology, or products.

The majority of the content in this OGC document is a direct copy of the content contained at https://github.com/AnalyticalGraphicsInc/3d-tiles/releases/tag/1.0 (the 1.0 tag of the 3d-tiles repo). No normative changes have been made to the content. This OGC document does contain content not contained in the 1.0 tag of the 3d-tiles repo.

Note: Some elements (such as Vector Data) contained in https://github.com/AnalyticalGraphicsInc/3d-tiles (the 3d-tiles repo) have been removed from the OGC document because they are currently under development and not a part of this specification. These elements are identified as future work in this OGC document.
