Hello, How can I implement collision detection (avoid camera collision to ground) ? I know this can be done with viewer.scene.screenSpaceCameraController.enableCollisionDetection = true; but I think it is used with touch navigation… but how can I do it when I use api like Camera.move/rotate/lookA…

Thank you Hyper Sonic, I solved it by computing camera height (relative to terrain height) with Cesium.sampleTerrain (with camera cartographic position). I do this on camera.moveEnd event and make a camera.moveUp() if it is less than a fixed limit. But this is not perfect as the camera first go u…

I suppose if the camera isn’t rolled or pitched the camera.moveUp method would work just fine, that’s good you got it working.
