GlassPro is an interactive software which simulates a realistic image synthesis of different glazing products on facades of buildings. GlassPro enables the user to visualize the rendering of a glazing product under a variety of lighting condition (overcast or sunny) and several interior design settings (with or without white/gray binds). GlassPro is intended only as a guide to the user to demonstrate the type of glazing products throughout the different stages of a building construction.
