The project supports extruding shapes and generating smooth normals for projected shapes. and i did it, i processed the data and i know where the polygons should located which i show them spheres. know the problem starting… i have the necessary coords but i dont know how can i pull the data and create an . Each polygon must include coordinates in WGS84 The Cesium platform provides the foundations any software application needs to utilize 3D geospatial data: visualization, data pipelines, curated data, and analytics. An Ellipsoid instance from the 3d-tiles-renderer project can be provided to the loader to project objects into the same reference frame A tool for topologically aware shape simplification. Reference systems: A standard "coordRefSys" member for explicitly providing the coordinate reference system ID used in the "place" geometry. Built with Globe. Requires [distance]. It uses the get expression to set a fill-extrusion layer's fill-extrusion-height, fill-extrusion-base, and fill-extrusion-color paint properties using values from the GeoJSON source.
