None of these answers Question 7 True/False: In an object with an alpha level of 1.0, you can see the objects that behind it? Select one: True False Question 8 True/False: The difference between WebGL and OpenGL is that WebGL only supports 2D graphics and OpenGL supports both 2D and 3D graphics. Select one: True False Question 9 The position that you are viewing a scene from is called the: Select one: 1. eye point 2. view reference point 3. viewport 4. view frustum Question 10 True/False: An orthographic projection, projects all of the objects in the scene to the viewing plane by parallel lines. Select one: True False Question 11 Which projection do the following objects represent? Select one: 1. Parallel projection 2. Orthographic projection 3. Perspective projection 4. Scaled projection Question 12 True/False: Clipping defines parts of the scene that you do not want to display. Select one: True False Question 13 Modeling an object about its local origin involves defining it in terms of: Select one: 1. modeling coordinates 2. eye coordinates 3. euclidean coordinates 4. modeling transformations Question 14 A vertex in graphics modeling defines a: Select one: 1. Point 2. Line 3. Polygon 4. None of these responses The correct answer is: Point Question 15 Which of the following shows obvious aliasing artifacts? Select one: 1. line a 2. line b 3. line c 4. line d Question 16 Which of the following is an antialiasing method? Select one: 1. pixel supersampling 2. geometry sequencing 3. unisample antialiasing 4. spatial aliasing Question 17 What geometry type will the following pseudo code generate? N = 12 set vertex at (1,0,90) for i = 0 to N set vertex at (1, 360/I, 90-180/N) Select one: 1. Triangle Fan 2. Triangle Strip 3. Quad Strip 4. Quad Fan Question 18 True/False: A transformation is a function that takes geometry and produces new geometry. Select one: True False Question 19 True/False: To rotate geometry 90 degrees you would use the translation form of transformation? Select one: True False Question 20 Which of the following types of transformations should be used to transform the picture on the left into the picture on the right? Select one: 1. Rotation 2. Translation 3. Rendering 4. None of these answers Question 21 True/False: Transformations are mathematical operations that map 3D space to 2D space and so mathematics has standard ways to represent them.
