vsgCs is a library for using 3D Tiles and other geospatial content within a Vulkan Scene Graph (VSG) application. In particular, it can download assets from a Cesium ion server.
For streaming and loading content, vsgCs uses the Cesium Native package, which also "powers Cesium's runtime integrations for Cesium for Unreal, Cesium for Unity, and Cesium for Nvidia Omniverse."

vsgCs and worldviewer have been tested with the Cesium World Terrain
and other imagery and tilesets available in the Cesium ion Asset
Depot. The OSM Buildings tileset works. For future directions, check
out our roadmap. Enjoy!
