The House of Illusion : Extending the Boundaries of Space As computer laboratories or studios in architecture schools provide greater access to fast machines and sophisticated software, the opportunity for computer aided animation increases I dimension. Previously the domain of the most enthusiastic, it has now become a relatively simple task to move from 3D to 4D. If the impediments to a common access to these new possibilities (for architects) are no longer a matter of the cost and availability of hardware and media, what measures the extent to which we can value the contribution of animation to studio-based design? This paper reports on our progress in establishing some practical and theoretical benchmarks comparing the cost with the value of computer aided (or mediated) animation.
