The analysis of visibility - environmental interactions between computer graphics, physics, and physiology

This article describes a new approach to determine the optical impression of objects on the landscape combining the standard methods of computer graphics, image analysis, physiological aspects of the human visual system, and physical conditions of the environment using the example of overhead lines. Well-known terms such as visibility or camouflage are described by figures resulting from a newly introduced simulation process. It can briefly be described as follows: (3D) reconstruction of the scenery in question. Selection of observer position and target object. Image formation. Image analysis. An application for planning overhead lines illustrates the result of this technique, respectively the importance of adequate visualization tools. (AGD)
