we moved from google earth to cesium too.
I have a problem about focusing a place in a multi building model .
Cesium only focuses to the center of the model and i can only give a camera view from the center or from the corner , but we need to show places between two buildings too.
i am sending a link below and you can see how we use cesium earth. You can use the left menu to see the camera angles.
Is there a way to unlock the "focusing center" of the model? we could do it very easily at google earth.
