Graphics

Question 1

What are simulating motion parts?

Answer 1

Dynamics: Applies laws of physics to determine position of objects
Kinematics: Applies characteristics of joints and appendages to determine position of objects
Avars
Motion Capture

Question 2

Local Versus Global Lighting

Answer 2

Local Lighting Model: Does not account for light interactions among objects
Global Lighting Model: Accounts for light interactions among objects
Ray Tracing
Radiosity

Question 3

Shading Techniques

Answer 3

Flat Shading: Creates faceted appearance
Gouraud and Phong Shading: Creates smooth, rounded appearance
Bump Mapping: Creates bumpy, rounded appearance

Question 4

Rendering Pipeline

Answer 4

Clipping: Restricts attention to objects within view volume
Scan Conversion: Associates pixel positions with points in scene
Shading: Determines appearance of points associated with pixels

Question 5

Reflection Versus Refraction

Answer 5

Reflection: Light rays bounce off surface.
Specular light
Diffuse light
Ambient light
Refraction: Light rays penetrate surface.

Question 6

Modeling Objects

Answer 6

Shape: Represented by a polygonal mesh obtained from
Traditional mathematical equations
Bezier curves and surfaces
Procedural models
Other methods being researched
Surface: Can be represented by a texture map

Question 7

2D Versus 3D Graphics

Answer 7

2D Graphics: Deals with manipulating two-dimensional images
3D Graphics: Deals with producing and displaying images of three-dimensional virtual scenes.
