If you have the two points, you can compute the vector direction by subtracting one from the other. Here’s a function you can use to get a rotation matrix from the origin and the vector. Lastly, you can use Quaternion.fromRotationMatrix to get a quaternion, and HeadingPitchRoll.fromQuaternion to …

Hello Gabby, I'm trying to follow your approach to determine the orientation between two points but I don't get correct results. I think the function you referring to is `Cesium.Transform.rotationMatrixFromPositionVelocity`? I created a Sandcastle example with my code (the blue cone should point t…

Nevermind, I got it working: [image] Cesium Sandcastle The Cesium Sandcastle provides an interactive environment for testing Cesium code. (my previous example applied a wrong transform for the orientation)

This is great! Thanks for posting your solution. I imagine this will be useful to a lot of others as well.

This is a great work of two points and a cone orientation drawing. Thanks for sharing your solution!

hello, can you send the code i got the same problem. thank you very much

I was able to use the example provided above to correctly orient a cone entity in the ecef reference frame, but my teams project is able to switch between ecef and eci. When switching to eci the cone updates to use the eci coordinates of my two entities, but the orientation is incorrect. Are there a…

Why doesn’t it work also for camera? viewer.scene.camera.flyTo({ destination: origin, orientation: Cesium.Quaternion.fromRotationMatrix( rotationMatrix ), complete: function() { // } });
