How does 3dmax exit the camera's field of vision?

1. First, create a cuboid in 3Dmax. As shown in the figure, the created box is obviously deformed because it still follows the camera's perspective.

2. Then, click the carmera option in the top tools menu, and then select any perspective from the pop-up options. Take the choice of TOP as an example.

3. Then, click the perspective option in the drop-down menu list.

4. Finally, as shown in the figure, the cuboid is displayed normally, so that the 3Dmax camera can exit the viewing angle successfully.
