Computer Graphics I

Question 1

Reflection vs Refraction

Answer 1

Reflection : Light rays bounce off surface
+Specular light
+Diffuse light
+Ambient light

Refraction : Light rays penetrate surface

Question 2

Rendering

Answer 2

Clipping : Restricts attention to objects within view volume

Scan Conversion : Associates pixel positions with points in scene

Shading : Determines appearance sof points associated with pixels

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

Consists of traditional algorithms for clipping, scan conversion, and shading

Question 5

Local vs Global Lightning

Answer 5

Local Lightning Model : Does not account for light interactions among objects

Global Lightning Model : Accounts for light interactions among objects
-Ray Tracing (ışın izleme)
-Radiosity (ışınsallık)

Question 6

Animation

Answer 6

Storyboard : A sequence of sketches summarizing the entire animation

Frame : One of many images used to create animation

Key Frames : Frames capturing the scene at specified points in time

In-betweening : Producing frames to fill the gaps between key frames

Question 7

Simulating Motion

Answer 7

Dynamics : Applies laws of physics to determine position of objects

Kinematics : Applies characteristics of joints amd appendages to determine poisition of objects
