How can depth be represented in a graphical user interface?
answer available for tutors only
In GUI the depth cues often indicate importance/activity level. Such cues are:
- size: larger objects appear closer.
- interposition: overlapping objects appear closer.
- contrast, clarity, brightness, texture: increasing any of these makes an object appear closer.
- shadow: generating a shadow of a foreground object and casting it on the background objects.
