Creating 3D mesh using GeoJson

Hi, the idea here is simple. I make an API call to receive a GeoJson file of a certain area. It has data pertaining to all the building in that area including the height and corner/vertex coordinates of the building. Now, I am trying to interpret this GeoJson file and create 3D meshes out of it. I have an overall understanding of how it can be done but Iā€™m struggling with developing the algorithm and looking for a low level guidance. Any help is greatly appreciated :slight_smile:
