I created a Cesium web app to view Gaussian Splat. But the issue is that they load so slowly that there is only empty space visible for couple of seconds. How to add a progress bar or something so users could interact with it inly after fully loaded?
It’s not entirely clear what the core of the question is. If this about the UI part of things, then most of that will likely depend on the framework that you’re using. For the CesiumJS side, in a more narrow sense, maybe you could use the allTilesLoaded event to wait until all tiles are loaded, and show some info message in the meantime. (I think that based on the current implementation, it might happen that all tiles are loaded, and still nothing is displayed, but that should then hopefully only a very short moment).
