Hey Selahattin,

Thanks for the video. Can you show how you’re loading your terrain? [Scene.pickPosition](https://cesiumjs.org/Cesium/Build/Documentation/Scene.html#pickPosition) should be returning the position reconstructed from the depth buffer. It looks like it’s only picking the ellipsoid perhaps? Does it look like the lines are drawn at the correct position when the camera is looking straight down instead of at an angle?
