The most direct mode of physical engagement with the material side of computer simulations today takes place in the interaction between architecture and games. Within this setting, perspective not only renders visual representations it also extends and modifies our perception. Physics-based simulations, procedural generation, robotic sensors, and augmented and virtual reality change the design, control and navigation of spaces. Data modeling and visualization merge into a novel tableau of different viewports and interfaces and offer a different perspective on the materiality of both architecture and games. This leads to a new relationship between the visuality, spatiality, and performativity of designed environments. This symposium aims to bridge fields such as architecture, computer science, media studies, design, game studies, and philosophy to discuss what has happened to perspective in media cultures of computer simulation.
