Deck 16: Computer Graphics and Entertainment: Movies, Games, and Virtual Communities

Question 1

________ occurs when a human animator specifies the starting and ending positions for an object, and the computer fills in the rest of the motion.

Answer 1

Keyframing

Question 2

Name the three steps in the graphics pipeline.

Answer 2

Object modeling, object motion, and rendering and display

Question 3

What is the role of a tessellation in CGI?

Answer 3

A tessellation provides a model of an object in three-dimensional spaces, a set of polygons that completely cover the surface of the object, and that may be described as a set of vertices of the polygons.

Question 4

What is a large group of computers used for rendering called?

Question 5

Name two ways that video games simplify their task in order to be able to render images in real time.

Question 6

A(n) ____________ environment is one in which user actions affect what is to be rendered next.

Question 7

Culling is a technique where pre-rendered objects are placed into a dynamic image.

Question 8

A video adds additional memory for high-intensive tasks, but uses the CPU to render video.

Question 9

After reading about the steps involved in computer-generated imagery, does it seem like more or less work than hand-drawn or stop-motion animation? What steps in the process are primarily technical, and where does the animator's creativity fit in?

Question 10

What are the pros and cons of online virtual communities and games like World of Warcraft and Second Life? Where do you think these virtual communities will be in 10 years?

Question 11

Will it be possible in the next two decades to "plug in" to a virtual reality and have it seem as though it's actually the real world? What kind of ramifications may this hold for the real world?
