Understanding Pictorial Space – II
An analytical drawing of spatial symbols clues which indicate distance and depth in our perception of form.
The primary visual cues which aid our perception of Depth:
- Binocular Vision
- Motion Parallax
Our eyes are overlapping fields of view and Stereoscopic Depth Vision.
The pictorial images created by graphic displays have to depend totally upon secondary cues to depth.
Depth is created by –
- Relative apparent size – Linear perspective objects become smaller as they are far away.
- Light and shadow
- Atmospheric haze (Ariel perspective)
- Overlap – most potent secondary cue to depth
