Scaling glTF with 3D Tiles
Cesium's Sean Lilley joined Tam Belayneh, Esri; Michael Beale, Autodesk; and Leonard Daly of The Khronos Group to discuss how to use glTF for large 3D models, terrain, scanned imagery, and connect it to GIS; Architecture Engineering, and Construction (AEC); and Building Information Model (BIM) meta-data to the individual nuts-and-bolts. glTF’s Geospatial Special Interest Group explained the limitations of today’s glTF and presented their solutions to extend it for the Geospatial and AEC industries. Hierarchical Level of Detail (HLOD), point clouds, geometry and texture compression, and meta-data solutions for the urban digital twin and how it applies to the Metaverse were additional topics discussed.
