A short outline of a new low cost methodology: we present the AsTrend, a new methodology for enhance and depict details of the 3D models. This technique is being revealed as an accurate method to study rock art carvings and inscriptions. We think that this method could be used by everyone as the main study objects are based in low cost photogrammetry on the acquisition of 3D models.

New possibilities to enhance
An outline of a new low cost methodology
We present the AsTrend, a new methodology for enhance and depict details of the 3D models. It is based on the extraction of LAS points from a tridimensional model, which are processed with the most common Lidar techniques (Hesse 2010).
The AsTrend (a LAS point methodology that is being proposed here), starts from the work of Hesse (2013) and is based on the combination of several of these techniques (Miller, 1994; Štular, et al., 2012).
This technique is being revealed as an accurate method to study rock art carvings and inscriptions like those which are proposed here. We expect to test this technique in other supports like bones, wood, pottery and so on. We also think that this method could be used by everyone as the main study objects are based in low cost photogrammetry on the acquisition of 3D models.
