The intersection of the altitude and azimuth defines the position of the sun relative to the building when using SunPath.
When generating images, these values are the co-ordinates from which the model is viewed to generate the image. They can only be directly input as whole numbers, but intermediary positions can be selected by using the button to Get camera position using Modelviewer, where the values of the selected position will then be automatically inserted in these fields.
