| 13 | |
Define illumination. How is the amount of illumination reflecting from a surface calculated? |
| | |
|
|
|
| 14 | |
What is the difference between diffuse and specular reflection? Is the same information needed for modeling both of them? |
| | |
|
|
|
| 15 | |
Name three different shading techniques. Compare them and describe how they differ from each other. Identify types of real world materials and objects which the shader is suitable for rendering. |
| | |
|
|
|

What is the difference between hue and saturation? If two colors only differed in saturation, would they have different HSV values? If so, which values would be different? Would they have different RGB values? If so, which values would be different? |
| | |
|
|
|
| 17 | |
What is the difference between saturation and value? Do colors lighten in value as they become less saturated? |
| | |
|
|
|
| 18 | |
What HSV values are changed by a shader simulating a white light? What if the light is a color other than white? |
| | |
