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.).
