, Wireframe
What is raster?
1 bit and 3 bit - ANS A field of points that can be turned on and off with different colors. The
whole field presents a complete graphic. Think of it like an image. (bitmap)
Depth of color depends on memory in bits per pixel.
1 bit (Monochrome)
Black or White, 1 on-off switch
3bit (Primaries)
Each pixel has 3 on-off switches
**SCALING CAUSES DISTORTION**
What is vector? - ANS A set of simple geometric features with mathematical features.
Can be scaled without distortion
Describe Electronic Engineering Drawings - ANS Allows for easier drawing modification and
duplication.
Simplifies the transfer of data
Reduce paper use [Not really though]
