I’m currently looking to implement the display of polyline volumes using 3d tiles. I know that the work on vector 3d tiles is still in progress (https://github.com/AnalyticalGraphicsInc/3d-tiles/tree/master/TileFormats/VectorData) and there’s no support for polyline volumes yet.
I’d like to start working on this part of the specification. So far I’ve been able to write a 3d tile generator for 3d polylines and I’ve been able to load the resulting 3d tile into Cesium using the 3d-tiles and vector-tiles-polylines branches (see screenshot).
At this point I’m looking for a bit of guidance on how I should start approaching the development of polyline volumes for 3d tiles.
I’m guessing I’ll need to create a “GroundPolylineVolumeBatch.js”, related fragment and vertex shader and then tie the code to “Vector2DTileContent.js”? How should information about the shape function be serialized?
Any information and some direction would be greatly appreciated.
