Explain the advantage and disadvantage of Raster CRT
Advantages
- Allows solids, not just wireframes
- Leverages low-cost CRT technology (i.e., TVs)
- Bright, i.e. display emits light
Disadvantages
- Requires screen-size memory array
- Discreet sampling (pixels), i.e. the lines are not straight anymore as in random scan display device. The lines now consist of pixels that may lead to jig jag
- Practical limit on size (call it 40 inches)
- Bulky
- Finicky (convergence, warp, etc.).
