In this paper, XfaceEd, our open source, platform independent tool for authoring 3D embodied conversational agents (ECAs) is presented. Following MPEG-4 Facial Animation (FA) standard, XfaceEd provides an easy to use interface to generate MPEG-4 ready ECAs from static 3D models. Users can set MPEG-4 Facial Definition Points (FDP) and Facial Animation Parameter Units (FAPU), define the zone of influence of each feature point and how this influence is propagated among the neighboring vertices.
