1. A concise explanation of the problem you’re experiencing.
I’m trying to simply follow a billboard movement on its trajectory, and keep the original camera HeadingPitchRange.
To do so I use 'viewer.camera.lookAt(myBillboardposition, new Cesium.HeadingPitchRange(camera.heading, camera.pitch, camera.range));
The problem is that each time I call ‘viewer.camera.lookAt’ the heading and the pitch of the camera is a bit modified,
so during the time the camera change a lot, and it’s not what I’d like to have.
2. A minimal code example. If you’ve found a bug, this helps us reproduce and repair it.
viewer.camera.lookAt(myBillboardposition, new Cesium.HeadingPitchRange(camera.heading, camera.pitch, camera.range));
