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.).
