Recent advances in computer graphics hardware and techniques have made it possible to visually render and explore geometrically-modeled settings in real time or at interactive rates. Computer simulations can generate significant spatial and temporal data describing three-dimensional environments. Computer graphics visualization techniques provide the means to display this multidimensional data, allowing substantial amounts of information to be communicated to the designer. This research concerns the development of simulation techniques to improve the accuracy of lighting and acoustic space evaluation, utilizing theoretical and interactive techniques. In addition, new interaction paradigms are under consideration.
