Abstract
One of the weaknesses in augmented reality (AR)
scenes is that, most of the times, the virtual model lacks realism
and is not integrated sufficiently into the scene to be credible. The
problem lies in lighting conditions differences from real
environment and virtual objects superimposed. This problem
takes on special significance indoors, to visualize interior design
proposals, because a non-integrated scene may seem unlikely and
unattractive. In this paper, we describe a teaching experience
conducted in the framework of an interior design specialization
course. It was carried out by students from the School of
Building Construction of Barcelona in November 2011, at the
Polytechnic University of Catalonia. Students were required to
use AR freeware tools for modeling and visualize their own
proposals indoor. The challenging task was to make virtual
objects blend harmoniously into the real scene, so they should
appear as if they were like real. New modeling techniques have
been experienced in order to add lighting conditions maps to
virtual objects. We used for that radiance and global illumination
simulations from the real environment to get real scene lighting
information. Experience was useful to determine the consistency
of illumination between the virtual objects and the surrounding
real objects in the scene, as well as, to evaluate the importance of
the use of this technology in interior design proposals and
architectural visualization.
