The Relationship between Visual Illusion and Landscape Drawing

Abstract

The geometry of linear perspective of landscape drawing and rendering remains one of the long standing scientific problem that has not been solved because its experimental behavior lacks theoretical explanation as a visual phenomenon. This study suggests the use of Ophthalmology and Geometrical Optics to explain the real geometry of linear perspective. It utilizes eye geometry to answer the question: why seen objects vanish in/around the horizon line? Or the question; what do eyes do to maintain the vanishing attitude. For answering these questions, the geometry of optics should be put to a comparative analytical research under a hypothesis that says: there is a different geometry of visual optics than both the geometric performance of linear perspective and the nowadays believes about visual optics. The new visual geometry is based on eye contribution of a shape of a pyramid or a cone of visual rays which are responsible for the vanishing attitude on the horizon. The eye contributes four cones or pyramids of visions that stand with the seen figure down to the retina of the eye up to the horizon.
