Hi! I recently worked on a project that implements direct COPC loading and visualization in CesiumJS without converting the data to 3D Tiles.
The project is now deployed and available here:
It may be useful as a reference for anyone looking to load COPC directly in a CesiumJS viewer. The implementation is still evolving, so feel free to open an issue if you find any bugs, have feature requests, or have ideas for improvement. Any feedback would be very welcome!
