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:

  1. Binocular Vision
  2. 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 –

  1. Relative apparent size – Linear perspective objects become smaller as they are far away.
  2. Light and shadow
  3. Atmospheric haze (Ariel perspective)
  4. Overlap – most potent secondary cue to depth

Pictorial Space | Secondary cues to Depth

The aim of this drawing is to translate analytically an object into differing perceptions responding to four of the secondary depth cues.

  1. Relative apparent size – (Linear perspective) objects become smaller as they moveaway.
  2. Light and shadow
  3. Atmospheric Haze (Darker frontal tones to lighter variations in the background – through values/ or dotting technique)
  4. Overlap – contour drawing – boundaries
Here’s an Exercise that will help you understand the concept:
  • Design and draw a series of black and white bands on a sheet of paper with different thicknesses and widths.
  • Crush the sheet into a paper ball
  • Partially open up the paper ball into free standing mass of lines, form and space.
  • Place it under a strong light and draw four sketches

The image below is an example of the Exercise for understanding the concept of Pictorial Space.
