Abstract

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
