Whats the purpose of the terrain


First of all thank you for this awesome framework.
Just want to know whats the purpose of the terrain and why is that when I load my point cloud without a terrain, it floats above the map layer.

But after loading the terrainProvider: Cesium.createWorldTerrain(), it sticks at the ground.

I think you answered your own question, no? :slight_smile: Any model that are created using real-world coordinates would not fit on an earth represented by a simple ellipsis with a flat surface. The added terrain is based off real-world coordinates, and fits with your model well. Remove the terrain, and the model will float in the sky against a flat non-real-world surface.

Thank you so much for the clear explanation! :grinning:


Recognize that the “quality” of the Cesium World Terrain differs from region to region and your point cloud may not conform well in certain areas.
