Abstract

Visibility of focal points is the result of visual information on the retina and how the form is perceived. Developing the principles of visibility of focal points requires understanding the visual space in the "horizon dimension" and "distance dimension" and background signals. How can the focal points (urban landmarks) be located based on the visual illusion and the effects of the background (annoying) elements? In general, the purpose of this study is to develop a methodology that can be used to increase the visibility of the focal points of the city by arranging buildings and designing urban space and architecture Research is developmental in terms of nature and causal method in terms of purpose. Geometric modeling and virtual reality techniques were used to measure the relationship between physical structure, visual perception, and visual illusion. A case study of the focal point and indicator of the holy shrine of Razavi and sidewalk buildings of Ayatollah Vaez Tabasi was modeled with sketch up software. Based on the research literature, there is a point (M) in the visual corridor, where, based on binocular vision, the height of the focal point and the marker are equal; before that, the focal point height is perceived higher than the marker height but after that, is perceived smaller. Therefore, based on geometric calculations, the position of point M was modeled according to the height of the focal point-marker and the distance from the focal point to the marker. according to the three-dimensional model of Ayatollah Vaez Tabasi sidewalk to the holy shrine of Imam Reza by virtual reality technique, the accuracy of the model was confirmed. Therefore, the arrangement of urban signs should be done following this issue in urban space.
