From the intro: “Real-time visual simulation technology has the potential to radically alter our understanding of historic urban environments. Unlike fixed computer animations, real-time technology allows interactive exploration of the modeled site, thereby creating unprecedented opportunities for experiential interpretation and innovative pedagogy. The World’s Columbian Exposition of 1893 is a perfect test case for the educational applications of interactive computer models. The exposition was a milestone for American architecture and urban planning. As Director of Works, Daniel Burnham coordinated a team of the most notable architects in the country, each designing one of the fair’s major buildings.”
