Conversion relationship between camera height and visual rectangle

I want to simulate the visual areas (exent) with different heights without changing the xy center and View width height. How can this be achieved?


Could you please share a little bit more information on what you are trying to accomplish? More information on your use case would help me provide better support. For instance, what do you mean by simulate visual areas? What is the xy center? I am looking forward to learning more!
