Interoperable Simulation and Gaming (ISG) Sprint

Sprint Week activities were conducted virtually on September 21-25, 2020, and results will be released in the near future.


The goal of the Sprint is to advance the use of relevant OGC and Khronos standards in the modeling and simulation community through practical exercise and testing of the draft specification produced by the 3D Data Container and Tiles API Pilot (YouTube Playlist) Of particular interest is the handling and integration of glTF models coming from multiple sources. There is secondary interest in the spec's implementability, consistency, completeness, and maturity. Implementation experiences obtained from the Sprint will advance the interests and work of the OGC Interoperable Simulation and Gaming Domain Working Group (ISG DWG) and of the OGC Standards Baseline in general.


This initiative is being sponsored by U.S. Special Operations Command (USSOCOM). Proposals from both OGC members and non-members were considered, and nine organizations were selected for participation. Stipend funding is being provided to selected OGC members.


The event will be a week-long, virtual coding sprint. The sprint will prototype organization-chosen features. A single prototype of the entire spec not feasible, but collectively we hope to reach as far as possible.

The the 3D Data Container and Tiles API Pilot project was built upon work from Testbeds 13 through 15, 3D Tiles, and I3S; combined with the introduction of resource-oriented OGC APIs built on the OpenAPI framework. These provide the foundation for the draft specification that is the test subject for this Sprint.

Several OGC members participated in the Pilot along with the OGC, Khronos Group, and an initiative sponsor to develop the draft spec. This spec allows 2D assets (maps, vector graphics), building data, and 3D assets (glTF models, OGC building models, digital elevations) to be used together to produce a synoptic view of the region in question. 


The Sprint Week event took place on 21-25 September 2020. A full schedule appears below.
