Java ideal for this application because it is an object-oriented language that allows dynamic extension and reconfiguration. The system uses sets of external classes for each actor (called 'evaluators') that modify arrays of parameters passed to them. This provides a flexible method of controlling objects by specifying object data in terms of arrays of numerical values and then using evaluators to modify these. The implementation allows these external classes to be loaded either from a known repository for evaluator classes (the simplest scheme) or by using a 'ClassLoader' to load classes from locations specified at run-time. A search agent can be used to find the classes that march a specification stored in a pre-defined format, and the use of partial matching can yield interesting side-effects on unspecified parameters. The scheme is therefore dynamically re-configurable with the possibility of actors in an animation finding and changing their behaviour over the lifetime of the animation by locating and retrieving new evaluator classes. A test-bed has been developed for the scheme that uses simple VRML geometries controlled by the behaviours.","PeriodicalId":155755,"journal":{"name":"Proceedings. Computer Animation '97 (Cat.

We divide the space containing the spheres into uniform subspaces of cell structure. Each sphere intersecting a subspace is tested against the others intersecting the same subspace for possible collisions. We identify three types of events to detect the sequence of all collisions during our simulation: collision, entering, and leaving. The first type of events is due to actual collisions, and the other two types occur when spheres move from subspace to subspace. By tracing all such events in the order of their occurring times, we are able to simulate n moving spheres with proper collision response in O(n/sub c/ log n+n/sub e/ log n) time with O(n) space after O(n log n) time preprocessing, where n/sub c/ and n/sub e/ are the number of actual collisions and that of entering and leaving events during the simulation, respectively. Since n/sub e/ depends on the size of subspaces, we adopt the collision model from kinetic theory for molecular gas (Feynmann et al., 1963) to determine the subspace size that minimizes simulation time. Experimental results show that collision detection can be done in linear time in n over a large range.","PeriodicalId":155755,"journal":{"name":"Proceedings. Computer Animation '97 (Cat.

It does not consider auditory scene analysis, which describes the ability of listeners to separate the acoustic events arriving from different environmental sources into separate perceptual representations (streams). The concept of auditory scenes relies on our everyday perception of sounds in daily life. It assumes various perceptual attributes such as duration, volume, position in space, and others, for each individual sound in the scene as well as the temporal, spatial and other relationships between them. Different temporal relationships and some theoretical considerations regarding these issues are presented in depth. The two grammars represent (1) the hierarchical and (2) the autonomous concept. The first grammar approach is similar to music composition and is basically a temporal composition of everyday sounds. By contrast, the second grammar approach defines the event driven non-hierarchical composition of everyday sounds. Before these grammars are discussed, an introduction to the use of sounds in man-machine interaction and the concept of auditory scenes are presented.","PeriodicalId":155755,"journal":{"name":"Proceedings.
