....(2) Calculus efficiency vs. memory space occupation. 3) static vs. dynamic Topology for animation. The hierarchy basic component, named the #######, is chosen to retain the geometric, topological and display information sufficient to set a frame in a 3D space[18] In a way similar to [22], an additional functionality can be associated to a ####### through the binding of one typed structure. If a ####### has no associated information it is said to be of ####### type. It can be useful as an intermediate frame to identify some functional location. In figure 2, each small black box ....

Daemons are executed in order of their activation time, which corresponds to breadth first traversal of the dependency graph. Daemons can thus be used to perform discrete simulations, as it is done in Belie [41]. Examples of VB2 s daemons are inverse kinematics simulation for articulated chains and scene rendering triggers. 3.1.4 Variable Paths In VB2, daemons, reactions, and constraints locate the variables through indirect paths. An indirect path is an object able to compute the location of a ....

Another of the objects developed for the microworld is a robot arm that can play catch , with a user using the Dataglove, using inverse kinematics techniques. Brett87] Sturman89] Zeltzer88] 2.3 Interactive Video Games The introduction of direct computer user interaction with the appearance of the MIT TX 0 2 was soon followed by the introduction of the first interactive video games. Spacewar, a game developed at MIT in 1961 for the DEC PDP 1, for the first time presented a user ....

....in some interframe synthetic movies. Instead, these movies are driven directly by software state machines or constraint systems. Indeed, examples of these may be more numerous than explicitly defined movies. They include interactive video games, flight simulators, interactive graphical simulators[Zeltzer88] and many applications at the user interface. 30 Chapter 4 Video Finger: An Example Synthetic Movie This thesis presents an example implementation of a synthetic movie, Video Finger. Video Finger is an application which uses a synthetic movie to convey information about the state of the ....

....The virtual world and its objects can be represented by three dimensional stereoscopic images and sounds. They are directly manipulated by a person through hand and body movements, and spoken words. Objects in the world may be linked to collections of data or to concurrently running simulators [1 4]. The technology brings together diverse elements including networked systems (possibly heterogeneous) specialized input and output devices, 3 D graphics, hand or body gesture and speech recognition, data visualization, distributed processing, simulation and the possibility of more than one user ....

....Pentland and Williams [1989] use vibration mode ( modal ) dynamics, a method of breaking down non rigid dynamics into the sum of independent vibration modes. Various integrated dynamics systems have been developed in the past decade: Interactive Dynamics [Witkin90] ThingWorld [Pentland90] Bolio [Zeltzer89], Virtual Erector [Schrder90] Each approaches computational dynamics in a different way, specializing in modeling certain behaviors. Few systems exist that have integrated virtual and real world imagery. ARGOS [Drascic93] provides a virtual pointer into the real world; Bajura et al. 1992] have ....

....for a wide variety of data types (distance, color, time) Partly due to this, we adopted a convention that all bounded scalar parameters to Alice calls would range between 0.0 and 1.0. Magic ranges like 0. 255 and 0. 32767 do not hold much appeal for novices. RELATED WORK LOGO [16] Bolio [25], and the Alternate Reality Kit (ARK) 19] and the animated Self programming environment [22] were all strong influences in the Alice project. Smalltalk [6] and HyperCard [13] both demonstrated that programming in the small was feasible by nonprogrammers. The Simple User Interface Toolkit (SUIT) ....

....in this paper is developed to address these concerns. 2 Previous Work Other groups have worked on support for this user interface style. Zeltzer and his colleagues at MIT produced a general purpose package for building interactive simulation systems, especially for task level animation systems [Zeltzer 1989]. The key element in the package is a constraint network to which all the objects are connected. Once the status of an object is updated, all the constraints which involve this object are informed and evaluated. By using constraint propagation, the gestural input from the DataGlove can also be ....

The MR Toolkit encourages a program structure that increases application portability. 2 Previous Work Zeltzer and his colleagues at MIT produced a general purpose package called bolio for building interactive simulation systems [24]. In bolio, a constraint network connects all the objects in the application, including the DataGlove. The DataGlove dependent constraints evaluate the current gesture, causing subsequent constraints to be executed, producing the reaction to the user s activity, which is displayed. One ....

BOLIO The Bolio system is the name given to the Integrated Graphical Simulation Platform (IGSP) designed and built by Zeltzer s group at the MIT Media Lab [BRET87][ZELT89A][ZELT89B] The interesting point of this system is the use of reusable modular components that can be linked at compile time to form a tailored system. This has allowed the system be used for such diverse research projects as insect locomotion, teleoperation of robotic arms, user interaction, and ....

....as long as the routines conform to the standard interfaces. The graphics routines are slightly more specific due to the nature of the graphics calls and platforms. It is this flexibility and reuse of code that has allowed one single set of software to be used for a diverse set of applications [ZELT89A]. An excellent overview on how Bolio can be used as a harness for task level animation can be found in [BADL91] The flexibility does not come free of cost. Bolio is capable of supporting only eight simple polyhedral objects at five frames per second [DWOR91] Part of this is due to the platform ....
