Resum

An in-house software for Computer Assisted Virtual Environments (CAVE™), called 3D Stereo Virtual Drawing Tool (3D stereo VDT), is presented through the interpretation of bedding and structural elements in two virtual outcrops. The main purpose of this software is to perform geological interpretations of point clouds through a friendly interface. 3D trackers allow the drawing of points and lines. Such elements may represent all sorts of geological features: bedding, unconformities, fractures, fold axial surfaces, axes, etc. One of the outcrops is a small, close-range point cloud constructed using feld photographs of a beach clif, whereas the other is a bigger, aerial point cloud built with Google Earth images of a valley slope. Both irregular and partly inaccessible outcrops consist of folded and faulted Palaeozoic rocks in the northwest portion of the Iberian Peninsula. The 3D analysis of these outcrops allowed us to supply new orientation data as well as ideas regarding the characteristics, origin and evolution of the mapped structures in relation to their setting.
