Perspective Versus Parallel Projection
- In perspective projection, parallel lines appear to converge to a point at
infinity. This is the default projection mode.
- In parallel projection, parallel lines appear to remain parallel to each other
as they extend to infinity. (Parallel projction is of limited usefulness in
three-dimensional visualization, but can be used to "line up" cells or vectors.)
- To switch projection mode, Click the Action menu, select
Set Projection To, and then select either Perprective or Parallel.
Note:
- Zooming is not synchronized between perspective and
parallel projection modes. The amount of zooming in one projection mode is
independent of the amount of zooming in the other projection mode.
