Creating and loading big 3D objects into Cesium












2















I'm trying to create and load 3D objects into Cesium.
I need to create these objects programmatically (by using some import-transformation service, .NET platform used) from various sources



I have experience of doing it in THREEJS.
I read DXF file, convert entities into PostGIS geometries, triangulate (to create surface from elevation data), tessellate geometries and finally construct
THREEJS-compatible scene (JSON format, Gzipped, THREE.BufferGeometry used). This works pretty well: no problems with loading hungreds of thousands triangles/points.
Sometimes I use webworkers just to request and parse JSON.



Also, I was able to load pretty big (40mb) geojson into my OpenLayers client app without any problem (Map and WebGLMap)



But I can't load even 20mb geojson (polylines) into cesium (1.51.0)!



viewer.dataSources.add(Cesium.GeoJsonDataSource.load('data/geojson/test1.geojson'));


gives me



An error occurred while rendering. Rendering has stopped.

at r (http://localhost:9090/public/ThirdParty/Cesium/Workers/combineGeometry.js:231:18552)


Why is that?
What can I do? GLTF/GLB/3D tiles are pretty complex formats. There is no rich tool set to customize/control object creation using these formats.
I do not want to buy super-duper (really) FME Server to create GLTFs...
Maybe I can use czml to load complex geometries, using polylines etc)?
