Detect Terrain and Line intersection point

[Hazel-Leylak]

Hi Community,

I want to calculate the intersection point where line and plane intersect like in the photo. Is it possibile to get this intersection point?

Thank you for bringing this question to the community! Intersection detection is a very common CesiumJS question. What kind of objects are you looking to detect the intersection of? In the meantime, I recommend checking out these community forum threads. I believe that they address similar questions.

I want to find the intersection points where a polygon intersects a terrain

Hi there, Is there any way to find the intersection points where a polygon(having height) intersecting terrain. The Cesium version you're using, your operating system and browser. Cesium 1.52, Win 10, Chrome

How to get intersection of a ray from the camera and 3d terrain?

1. A concise explanation of the problem you’re experiencing. I need to get the intersection point of a ray from the camera to 3d terrain. Cesium.IntersectionTest() seem to use only the ellipsoid, 2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it. var intersectionPoint = function(){ var ellipsoid = viewer.scene.mapProjection.ellipsoid; var windowCoordinates = new Cesium.Cartesian2(elmnt.offsetHeight / 2, elmnt.offsetWidth / 2); var ray = viewer.camera.…

Please let me know if you have any other questions or concerns. I am looking forward to learning more!
