I have a shapefile containing about 50,000 building footprint. The aim was to view them as 3dtiles in Cesium.
The steps i did was
Extrude the building footprints based on it’s attribute height and export to collada (single file). this is done in Arcgis pro. Viewed in Cloudcompare. looks good.
Convert using collada2gltf to get glb file. Result in a single file,say building.glb
Convert glb file to 3dtiles via glbTOB3dm. Result in a single file, say building.b3dm
File size is the same as the glb file.
I guess i missing something here. Looking at the samples context capture Marsellie, the b3dm are small and many.
My questions are do i export Step 1 as a single collada file for every building.
If yes, after reading on the list abt tilesets, how do i go about creating the tilesets to bind the b3dm files together.
