I have a use case in which i need smooth tile loading, and i need to make it as perfect and seamless as possible. The solution that comes in to my mind is that to pre-load the tiles of an area of interest (at specified zoom level), and when i zoom into that area then cesium should fetch those tiles instead of making a network request every time the camera changes location. Is this thing even possible in cesium? If not, then is there any other solution to tackle this problem?

Hi there,
We don’t have any preload functions currently (because often this goes again a data provider’s terms of service), but we wouldn’t be opposed to adding such functionality in the future. We’re happy to look at a pull request!

Hi,
Have you made any progess regarding a preload function for tiles? My use case would be to preload local tiles (at different zoom levels) into RAM before letting the user interact with the viewer.
Thank you,
Dorian.
Preloading is still something we’d like to see, but isn’t something we’ve had a chance to develop yet. The latest here is an overhaul of the terrain/imagery loading to reduce the number of tiles that get loaded and make everything feel a lot more response. You can read more on that here:
