There is a requirement that a random image of the size be placed in the scene. It is necessary to calculate the size of the scene and the wall to ensure that objects can be observed, and that the characters need to stay on the ground
A typical approach of viewers is to compute the bounding box of the scene and then compute the related center and size properties to position/orient the camera. You can find some code for this here:

Please help me achieve it
