Perspective vs Orthographic - Interactive 3D Graphics

  • 0:00 - 0:04
    Unlike a fish-eye lens, lines remain straight on the screen with both a
  • 0:04 - 0:09
    perspective and an orthographic transform. Normal perspective matrices cause
  • 0:09 - 0:13
    distant objects to appear smaller. Orthographic do not. The Z depth varies
  • 0:13 - 0:17
    nonlinearly with perspective. It's linear with orthographic. The nonlinearity
  • 0:17 - 0:20
    for perspective is connected with the fact that lines stay straight when
  • 0:20 - 0:25
    transformed. In perspective, parallel lines usually meet at a vanishing point.
  • 0:25 - 0:28
    Orthographic is useful in computer-aided design, because lines are made
  • 0:28 - 0:29
    parallel.
