vsgCs — 3D Tiles and Cesium ion for VSG

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."

Features

• Streaming of geospatial assets into a VSG scene graph

  • 3D Tiles tilesets with glTF models
  • Cesium ion assets

• Multiple tilesets in a scene

• Image overlays on tilesets

  • Multiple layered overlays with individual alpha values

• Whole-Earth terrain paging

• Example viewing application
