"Solid Hollows" and "Reverspectives": Similarities and differences

Area of Science:

• Visual perception
• Art and optical illusions
• Cognitive psychology

Background:

• Patrick Hughes' artworks, "Reverspectives" and "Solid Hollows", challenge conventional visual perception.
• Reverspectives feature protruding pyramids that appear to recede.
• Solid Hollows present a receding structure that appears to protrude.

Purpose of the Study:

• To describe the similarities and differences between "Reverspectives" and "Solid Hollows".
• To analyze the role of perspective in the perception of these artworks.
• To investigate the interplay between perspective and binocular disparity in depth perception.

Main Methods:

• Qualitative analysis of artistic structures.
• Examination of perceptual phenomena in relation to geometric forms.
• Review of established theories on visual perception and depth cues.

Main Results:

• Perspective is a dominant cue in perceiving "Reverspectives", overriding binocular disparity at viewing distances > 50-100 cm.
• For "Solid Hollows", perspective contributes to the perception of reversed depth.
• The visual system's bias towards convexity influences the perception of "Solid Hollows".

Conclusions:

• Perspective is a primary factor, not a secondary cue, in the visual perception of Hughes' artworks.
• "Reverspectives" and "Solid Hollows" demonstrate the complex interaction between artistic design and human visual processing.
• These artworks offer insights into how the brain interprets depth and form, highlighting the power of perspective and inherent visual biases.
