Description
I'm currently working on a library for a LiDAR and wanted to make use of Mapbox GL JS for visualizing point clouds both in real-time (while driving your car) but also statically (for the route).
For this use-case here are the road-blockers I encountered.
1/ I'm not able to extrude points. I can hack around this with small polygons. But then it seems like this is roughly the smallest polygon I can get to show up (there's probably a filter for noise?):
2/ The extrusion feature seems to not support values < 1.
Here's what happens for a fractional 0.5 extrusion value:
3/ There is no streaming source. My plan was to either use a Websocket server pushing point clouds into the browser and updating a source or exposing a GeoJSON endpoint which changes every second.
I don't expect support for point clouds in the foreseeable future.
I just want to bring blockers for the point cloud / LiDAR use-case to your attention.

Research direction
The issue identifies three broad blockers: point extrusion, fractional extrusion values, and streaming point-cloud sources. No files, tests, or entry points are named; review the existing extrusion and source-update behavior first, then clarify scope and acceptance criteria with maintainers before starting.
