Cameras James Martin High School Computer Multimedia and Animation Instructor: G. Patton From: CHAPTER 11 – 3 DS MAX AND ITS APPLICATIONS

1. What does the term camera mean in 3 ds max? • In 3 ds max, camera refers a point of view from a virtual camera used to display a scene, similar to that from a still camera or videocamera.

2. What are the different types of cameras in 3 ds max? There two types of cameras in 3 ds max: • Target • free

3. How do the types of camera differ? • A target camera consists of the camera itself as well as a target. The camera and target can be moved independently. • A free camera does not have a target and must be aimed by transforming the camera.

4. What effect does changing the display color of a camera in the Name and Color rollout have on the scene? • It has none. The display color of a camera cannot be changed using the Name and Color rollout.

5. What must be used to draw a camera? • The cursor is used to draw a camera into a scene

6. Which camera has an invisible target used when the camera is orbited? • The Free Camera

7. When a camera is created, unselected and reselected, in which rollout and under which tab of the Command Panel are its parameters set? • Parameters > Modify

8. What aspect of a camera is the value in the Lens: spinner? • Focal Length

9. What are the functions of the buttons in the Stock Lenses area? • The buttons in the Stock Lenses area are used to select a common, “real-world” lens for the focal length of the camera

10. What is meant by the phrase field of view? The field of view refers to: • the “width” of the camera or • how much the camera can “see” from sideto-side.

11. What do the buttons in the field of vision (FOV) flyout allow you to do? • The buttons allow you to change the way the FOV is calculated.

12. What does the Type: drop-down list in the Parameters rollout for a camera allow you to do? • The Type drop-down allows for a switch between camera types.

13. What are clipping planes? • Clipping planes are “starting” and “ending” points that determine what the camera “sees” in a scene. • Clipping planes are set at specified distances along the camera’s local Z axis.

14. What is camera motion blur used for? • Camera motion blur is used to simulate the natural blur produced by fast moving objects

15. What is meant by the phrase safe frame? • The safe frame is a rectangular display that shows what will be rendered in a camera viewport.

16. What is the purpose of camera matching? • The purpose of camera matching is to match the perspective of the camera to that of a bitmapped image. • This is a very useful technique for combining liveaction footage and computer animation

17. What are two ways to perform camera matching? • Camera matching can be performed by displaying the bitmap as a background in a viewport and matching the camera’s horizon to that of the bitmap. • It can also be performed by using the Camera Match utility and placing Cam. Points.

18. What is one example of when you may use linking with a camera? Possibilities: • A camera’s target may be linked to a model to enable the camera to automatically follow the movement of the model in an animation • a camera may be linked to a dummy object to animate the camera itself.

19. What is walkthrough? • A walkthrough is a visual effect in which the view moves through a building as though the viewer is walking. • Seeing through the eyes of a camera as if it were a person’s eyes.

20. What type of camera is typically used for a walkthrough? • Free camera is normally used for a walkthrough.
