    Although the widespread use of gaming for leisure purposes has been well documented, the use of games to support cultural heritage purposes, such as historical teaching and learning, or for enhancing museum visits, has been less well considered. The state-of-the-art in serious game technology is identical to that of the state-of-the-art in entertainment games technology. As a result, the field of serious heritage games concerns itself with recent advances in computer games, real-time computer graphics, virtual and augmented reality and artificial intelligence. On the other hand, the main strengths of serious gaming applications may be generalised as being in the areas of communication, visual expression of information, collaboration mechanisms, interactivity and entertainment. In this report, we will focus on the state-of-the-art with respect to the theories, methods and technologies used in serious heritage games. We provide an overview of existing literature of relevance to the domain, discuss the strengths and weaknesses of the described methods and point out unsolved problems and challenges. In addition, several case studies illustrating the application of methods and technologies used in cultural heritage are presented

    Hierarchical path-finding for Navigation Meshes (HNA*)

    Path-finding can become an important bottleneck as both the size of the virtual environments and the number of agents navigating them increase. It is important to develop techniques that can be efficiently applied to any environment independently of its abstract representation. In this paper we present a hierarchical NavMesh representation to speed up path-finding. Hierarchical path-finding (HPA*) has been successfully applied to regular grids, but there is a need to extend the benefits of this method to polygonal navigation meshes. As opposed to regular grids, navigation meshes offer representations with higher accuracy regarding the underlying geometry, while containing a smaller number of cells. Therefore, we present a bottom-up method to create a hierarchical representation based on a multilevel k-way partitioning algorithm (MLkP), annotated with sub-paths that can be accessed online by our Hierarchical NavMesh Path-finding algorithm (HNA*). The algorithm benefits from searching in graphs with a much smaller number of cells, thus performing up to 7.7 times faster than traditional A¿ over the initial NavMesh. We present results of HNA* over a variety of scenarios and discuss the benefits of the algorithm together with areas for improvement.Peer ReviewedPostprint (author's final draft

    An Extendable Multiagent Model for Behavioural Animation

    This paper presents a framework for visually simulating the behaviour of actors in virtual environments. In principle, the environmental interaction follows a cyclic processing of perception, decision, and action. As natural life-forms perceive their environment by active sensing, our approach also tends to let the artificial actor actively sense the virtual world. This allows us to place the characters in non-preprocessed virtual dynamic environments, what we call generic environments. A main aspect within our framework is the strict distinction between a behaviour pattern, that we term model, and its instances, named characters, which use the pattern. This allows them sharing one or more behaviour models. Low-level tasks like sensing or acting are took over by so called subagents, which are subordinated modules extendedly plugged in the character. In a demonstration we exemplarily show the application of our framework. We place the same character in different environments and let it climb and descend stairs, ramps and hills autonomously. Additionally the reactiveness for moving objects is tested. In future, this approach shall go into action for a simulation of an urban environment
