They provide useful data to select specific building processes. Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method. Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured. This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily).

Teaching experience in interior design Authors: Sánchez Riera, Alberto; Redondo Domínguez, Ernesto; Fonseca Escudero, David 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.

The identification is developed through the analysis of some furniture, in which it is used a formal grammar identification as a means to find out and generate a project language. This language construction is based on the grammar that generates forms which correspond to the same language, through the recursive application of a set of rules. Thus, the paper tries to identify a specific grammar for the furniture through its digital modeling.
