dc.description.abstractIn this work, we focus our attention to near real time illuminance for Lighting CAD. The implemented model is the Basic Method CIE which is a simplified method used in interior lighting design; a pre-computational phase is required, for form factor evaluation, and it is done by the CPU while GPU is used for the direct component evaluation to render the pseudo color map of the computed result. Our approach offers a further improvement in comparison with traditional lighting CAD, since it allows lighting designer to obtain an interactive solutions and the interactivity is reached using graphic hardware, in fact the pre-computation process is independent from the position of luminaries into the scene. The presented method is applied on a simple geometry, a parallepided room, where the surface is assumed to show a Lambertian's behaviour, but the model can be improved to remove these limitation.en_US
