Abstract
This paper describes methods that can be used for modelling radiative properties of light sources and materials, in a radiosity computation algorithm. These methods have been designed in order to improve the photo-realistic rendering of complex architectural scenes as well as to allow illumination engineering applications. They are based on the accurate modelling of the spatial and spectral emittance distributions of the light sources, and the surface reflectance/transmittance distributions from measurement, and allow the exact colorimetric properties of the light sources and the surfaces to be calculate. A method for changing radiosity inputs during the radiosity process, without recalculating the solution entirely is also proposed. This allows modifications in design or dynamic lighting effects to be simulated more interactively,
