ITEC2110 Spring 2013 Test 3, Dr. Jim Rowan
Images used in this test are found in the folder named: test3Spring2013Images.
1) Looking at booleanImage1.jpg you see two spheres on the left that occupy some of the same space. What operation would you perform on these two objects to get the single object on the right?
2) Looking at booleanImage2.jpg you see two spheres on the right that occupy some of the same space. What operation would you perform on these two objects to get the single object on the left?
3) Looking at booleanImage3.jpg you see two spheres on the right that occupy some of the same space. What operation would you perform on these two objects to get the single object on the left?
4) BooleanImage4.jpg shows an object that could either be two spheres occupying the same space or the union of those two spheres. Why can’t you tell which it is?
5) BooleanImage5.jpg shows the wireframe of an object made from two spheres using what Boolean operation?
6)- What kind of model building technique does Blender use?
7) Looking at the images named test3Image1.jpg through test3Image5.jpg which one (or ones) show a motion capture setup?
8) Looking at the images named test3Image1.jpg through test3Image5.jpg which one (or ones) are an example of augmented reality?
9) Test3Image1.jpg shows video that is displaying an artifact that is the result of using what kind of video scan technique?
10) What is the video artifact seen in Test3Image1.jpg called?
11) Given the scan technique that produced test3Image1.jpg what else is needed to cause the artifact seen in that image?
12) Test3Image1.jpg is an example of one kind of video scan technique. What is the other scan technique called?

13) Digital TV recently replaced Analog broadcast TV. Give one reason for this change.
14) Give one advantage of analog broadcast TV that was lost with the conversion to digital broadcast TV.
15) What is it about human vision that chroma subsampling uses to reduce the size of the video stream?
16) Describe the basic problem encountered when converting motion picture film to video using any of the Telecine processes?
17) Mpeg.jpg shows three versions of MPEG compression (cleverly named 1, 2 and 3).
In that image you can see three different kinds of frames, the I, P and B. Which of these frames is a completely specified image on its own?
18) What is another name for that type of compression?
19) Temporal compression uses multiple frames to compress a single frame of video. We mentioned two forms of temporal compression in class. What are these two versions called?
20) When generating the frames between the key frames in an animation sequence there are two choices of interpolation. What are they?
21) What are the two different forms of animation that use 3D models?
22) What are the two different forms of animation that use 2D models?
23) When using 3D animation techniques (rather than 2D techniques) what two additional things must the animator take into consideration?
24) In 1937 Walt Disney brought Snow White to the screen using what form of animation?
25) The choice of the codec used to compress and decompress a video affects that video in a number of different ways. Give one of these other than video quality.
