How does 3Dmax make the camera rotate around the object? How to do camera animation?

Two key points are mainly used: "camera target selection" and "path constraint":

1. Draw a circle in the top view window with the "Figure"-"Circle" tool and adjust the center of the circle to the center of the object;

2. Mark "Target Camera" in the top view, press the right mouse button to select "Select Camera Target" and set the object as the target of the target camera;

3. Select Animation-Constraint-Path Constraint in the menu, and select the circle as the constraint object of the camera.

4. Change the "View" window to "Camera" window to watch or render the animation of the camera rotating around the object.
