Use of imaging techniques to obtain 3D models of small insects

Abstract

This paper explores a new way to apply knowledge in the area of physics to the artistic technique. Specifically, a new application for imaging techniques in the micrometric scale is proposed: the creation of 3D digital models of small insects which would be robust and precise enough to create physical models up to 10 meters of length while maintaining a realistic appearance. X-ray computed tomography is a technique widely used in the medical world to obtain 3D images of the interior of the body non-intrusively. In this study, micro-computed tomography (microCT) is used to gain a 3D model of a 2.5mm fruit fly. From this image, reverse engineering software is used to create a polygonal model of the sample, which is then repaired until fit for reproduction in a sculpture. © 2011 Springer-Verlag Berlin Heidelberg.
