© 2022, Education and research in Computer Aided Architectural Design in Europe. All rights reserved.A visibility algorithm has been developed and practiced on the iconic towers of Istanbul from various locations with multiple observation points. This research accepts visibility as a binary subject and limited subjective perspectives. Using visibility as a design strategy is a prevalent technique for designers. Applying visibility aspects to the design is an outcome of psychological research in the 60s. Benedikt was the first person who added visibility to his architectural studies. Visibility refers to being able to see or be seen from a distance. This research accepts and practices this definition on two iconic towers of the city of Istanbul with the model MoV (Model of Visibility) developed. The implantation of the developed model is represented with the voxel modeling method. To be able to provide volumetric data, voxel-based representation was explicitly applied to the digital models of iconic towers. This representation model aimed to illustrate and quantify the visible and non-visible areas according to the location of the observation point’s visibility range.
