Among 3D tools, photogrammetry has received growing attention for the modeling of under¬ground spaces. The flexibility of its implementation and the wide field that it can cover encourage its use for recording decorated walls and their contexts. As part of a developing program ANR microanalysis on prehistoric art, 3D photogrammetry modeling were carried out in caves in Blanchard (Indre, France) and Rouffignac (Dordogne, France). I make quickly reference at two examples which are developed in article: 1) the numbering and analysis of the condition of the walls and the engravings; 2) localization in 3D pointcloud of archaeological data (paintings, prints, objects of flint or bone stuck into the wall) and links with different kinds of information about them (type, descriptions, dimensions, drawing, etc.). These applications illustrate the possibilities offered by current 3D tools in the study of rock art, and are sometimes new ways for the study of prehistoric representations in their geomorphological and archaeological context

Analysis of prehistoric art is inseparable from the study of its supports, movable or on walls. Increasingly, this topic is included among the research aims of modern studies. The contribution of several techniques of restoration in 3D (scanner/laser, photogrammetry, microtopography, etc.) makes it possible to approach different graphic productions and their areas. Beyond the virtual modeling of wall, or decorated artifacts, it is interesting to make use of an adapted numeric support to incorporate and analyze natural, graphic and archaeological information (nature of area, engravings, paintings, flagged items, etc.). We propose here to make a comparison of each technique, to describe in detail its contribution and complementarity in the research of paleolithic art, using two examples. First, the Blanchard cave (Indre), now being studied as part of the MADAPCA research program subsidized by the Agence Nationale de la Recherche, second, the site of la Marche (Vienne).
