“The emergence of computer graphics as a powerful medium to communicate information is one of the primary reasons graphics is playing a larger role in engineering, science and technology. Such a powerful medium has emerged from many sources. The author suggests that there is a philosophical foundation and a unique body of knowledge necessary for a discipline called visual science. This emerging discipline has as its foundation spatial cognition, imaging and geometry. These three areas when combined provide the knowledge base for visual science. The applications for visual science can be grouped into two areas: artistic and technical.”
