Changing the camera's viewpoint in a reliable, repeatable way

Display Figure 9.

Assume you want to relocate the camera to a viewpoint that is:

• 10 meters from the center point of the ground
• 1.5 meters above the ground
• Oriented toward the northwest.

You can interactively call the following methods (the order is important)

• camera.setPointOfView(...)\ground
• camera.turn(...)\RIGHT\135/360
• camera.moveAwayFrom(...)\ground\10
• camera.move(...)\UP\1.5

Figure 9 shows the result after the first three of the above method calls.
