08$a88-351-3006-9 330 $aBramante's skill in controlling the creation of a seamlessly conceived space shows how architecture can exploit its representative capacity of internal perspectives, considered architecture integration. The key adopted to reach this result is the "architectura picta" of the built space. It adopts built space combined with small apparatuses to conceal the critical points in which the continuity between real and virtual space is resolved. The multiplication of centers amplifies the effectiveness of the perspective, making it convincing from several points of view, even for a moving observer. The implicit perceptual effect overcomes the geometric correctness, which was neglected to enhance its effectiveness as a tool for creating a global and augmented art "ante litteram". The research published in this volume documents, through a small number of selected cases studies, the unsuspected development in Lombardy in applying perspective decoration to architecture, understood in the broadest sense as the art of constructing artificial space. This latter consists of controlling the instruments of representation to improve perceptive involvement and visual communication. It underlines the continuity of Milanese perspective with the immersive spaces of augmented reality offered today by digital technology. 517 $aL'ereditą di Bramante 517 $aEreditą di Bramante 606 $aTheory of architecture$2bicssc 610 $aArchitectural Perspective 610 $aArchitectural Survey 610 $aPerception and spatial communication 610 $aPerspective 610 $aSpatial design 610 $aVirtual spaces 615 7$aTheory of architecture 700 $aRossi$b Michela$4edt$040079 702 $aRusso$b Michele$4edt 702 $aRossi$b Michela$4oth 702 $aRusso$b Michele$4oth 906 $aBOOK 912 $a9910556099903321 996 $aL'ereditą di Bramante$93028699 997 $aUNINA
