For decades, morphological research on human faces was performed either on the living subject, or by means of 2D photographs. Within the last few years and with the development of new systems we are now able to produce three dimensional models of human faces. The methods and tools for data acquisition, processing, and analysis of 3D shape and form are part of a new interdiscipline: Virtual Anthropology. We are combining several approaches to study sexual dimorphism in human facial morphology and to compare the perfomance and accuracy of different systems producing 3D facial models. With the Breuckmann optoTop-He®, we have a scanning system that is capable of performing three dimensional surface scans of almost every surface in realtime. FaceGen Modeller® and PhotoModeler 2010® on the other hand are software solutions that allow us to produce 3D models of human faces based only on several 2D photographs. The aim of this study is to examine if software using 2D images, although much cheaper than a full scale scanning system, can create 3D models of sufficient accuracy for scientific and other purposes. The results are important for both anthropological and forensic applications.
