Item Automatically Generating Virtual Humans using Evolutionary Algorithms(The Eurographics Association, 2009) Albin-Clark, Adrian; Howard, Toby; Wen Tang and John CollomosseAbstract Virtual Humans are used in many applications either as an embodiment of a real person (an "avatar"), or under the control of a computer program (an "agent" or "non-player character"). The automatic generation of Virtual Humans is a challenging problem if they are to look both plausible and unique within a population. We present an approach which exploits the power of Evolutionary Algorithms (EAs), and provide illustrative examples of how our methods may be realised within the context of surface-based model geometry.Item Visualisation of Blockplay in Early Childhood(The Eurographics Association, 2011) Albin-Clark, Adrian; Howard, T. L. J.; Anderson, B.; Ian Grimstead and Hamish CarrObservation of young children is common in educational settings. For trainee practitioners however, access to children is infrequent, and even then, only small amounts of observable activity can be captured. We have developed a cross-platform software application to support observations made by pedagogical practitioners. Our system combines game-oriented technology: 3D graphics, animation, physics and classical game artificial intelligence. The stages of blockplay are used to represent the physical play of characters, and social play stages and egocentrism define their behaviour. We present the graphical side of the system including visualisations options that expose the underlying functionality. The prototype system Observation which we believe is the first to employ 3D interactive computer graphics for visualising early childhood play, is available for download and evaluation.
