Abstract: THE SHADOWPACK PACKAGE OF COMPUTER PROGRAMS HAS BEEN DEVELOPED TO FACILITATE SHADING EVALUATIONS, FOR THE DIRECT COMPONENT OF SOLAR RADIATION, WITH GENERAL THREE-DIMENSIONAL MODELS. AN INTERACTIVE SOLID MODELLING PROGRAM ALLOWS THE USER TO CONSTRUCT AND VIEW THE THREE-DIMENSIONAL MODEL BEFORE SAVING IT FOR FURTHER ANALYSIS AND DISPLAY. OTHER PROGRAMS PERMIT THE GRAPHICAL DISPLAY OF THE SHADING SITUATION THROUGHOUT THE YEAR, THE QUANTITATIVE ASSESS- MENT OF ENERGY RECEIVED ON DIFFERENT FACES OF THE MODEL, AND THE DISPLAY OF THE DISTRIBUTION OF ENERGY RECEIVED ON PARTICULAR FACES BY MEANS OF CONTOUR PLOTS. THE USE OF THE COMPUTER GRAPHICS AP- PROACH HAS PROVED PARTICULARLY CONVENIENT BECAUSE OF THE SIMILARITY BETWEEN THE TECHNIQUES USED FOR GRAPHICAL AND NUMERICAL ALGORITHMS.
