I’m trying to zoom at the boundaries of a WMS layer. After some searching I found this solution:
destination: new Cesium.Rectangle.fromDegrees(bbox.left, bbox.bottom, bbox.right, bbox.top)
It works well when the SceneMode is 2D, but on 3D the zoom is larger than expected.
My suspections is that the setView is not considering the spherical projection,
I had a silimilar issue on getting coordinates, but I solved it using a GeographicProjection to calculate the values.
