Investigation on light effect on spatial illusion resulting from forced perspective

Abstract

AbstractLinear perspective is a drawing system that can transform geometry from conceptual form to perceptual, and thus it is an essential tool for designers to predict the spatial perception of proposed construction designs. Linear perspective is also identified as an effective pictorial depth cue that can provide the visual information necessary to retrieve the three-dimensional sense of depth from both the two-dimensional retinal images and drawn pictures. As a result, linear perspective has been used as an effective design strategy to create forced perspectives that can exaggerate the depth perception of architectural scenes. Light has also been observed to influence the perceptual judgment of depth in an architectural scene. Luminance contrast has been proven through perceptual studies conducted using the perceptually realistic computer-generated environment to be an effective depth cue that can create illusory depth effects. In this study, the interrelationship of the size and tone-related depth cue...
