Abstract
El desarrollo de la informática ha hecho que aparezcan una serie de tecnologías digitales susceptibles de ser utilizadas con fines escultóricos, entre las que se encuentran las de digitalización tridimensional. Estas pueden utilizarse en combinación con técnicas escultóricas tradicionales, sustituyendo a procesos como el moldeado o el pantógrafo y aumentando sus posibilidades a través de su capacidad para combinarse con técnicas digitales, capturar sujetos sin necesidad de tocarlos y en algunos casos incluso registrar estructuras que no son susceptibles de ser vaciadas. Dentro de la digitalización existe un conjunto de métodos particularmente interesantes por sus bajos costes y habitual facilidad de implementación: las técnicas de digitalización 3D y 2.5D basadas en imágenes RGB. No obstante, su uso dentro del ámbito de la escultura parece ser limitado, y no existe ni documentación simplificada que permita identificarlas y aprender a implementarlas, ni suficientes referentes artísticos que visibilicen sus posibilidades...
The development of computing has resulted in a series of digital technologies that can be employed in sculptural creation, amongst which are three-dimensional digitization ones. These can be used in combination with traditional sculptural techniques, to replace processes carried out by molds and pantographs and augment the possibilities they offer, thanks to their capacity to be combined with other digital techniques, to carry out contactless capture of subjects, and in some cases even digitize structures that can’t be molded. Within digitization exists a group of methods which are particularly interesting due to their low costs and usual user-friendliness: RGB image-based 3D and 2.5D digitization techniques. Nonetheless, their use within the field of sculpture seems to be quite limited, and there exists no simplified documentation that allows for their identification and for learning how to use them, nor enough artistic referents with which to bring attention to their potential...
