....user can specify object behaviours and interact with them, exploring various possibilities. However, due to the research nature of our work, we wished to implement new ideas that were previously unthought of, and as a result, making extensions within the existing framework would be difficult. VB2 [GOBB93] was designed to demonstrate the use of constraints to implement virtual environments. When trackers are updating, the constraint engine manipulates objects in the scene graph, allowing the user to alter the position and orientation of objects. However, constraints are only useful as a solution to ....

....upon is to combine these two roles (visible representation and control) into one directly manipulable object. Control will be performed using integrated three dimensional handles[CSH 92, ZHR 93] and supported using object oriented visualization environment design techniques[TGB 90, GBT93, FH94] The handles will have consistent functions and appearances across different tools. Tool selection will be controlled via voice commands, thus reducing the input devices to a three dimensional mouse and a microphone. 4.2 Interface Implementation A prototype of the interface design was ....

These constraints are added and removed as the user manipulates different objects in the virtual world. ffl The Kaleidoscope language ....

....with two dimensional worlds, it starts to show limitations when interacting with three dimensional worlds. Major drawbacks of this solution are the lack of correlation between manipulation and effect as well as the high degree of cognitive separation between users and the models they are editing [21, 33, 32]. The inadequacy of user interfaces based on 2D input devices and 2D mindsets becomes particularly evident in applications that require users to specify complex spatial information, such as 3D modeling and animation, motion control, or surface modeling. In all these cases, the low bandwidth ....

.... Optimizer) to high end professional packages (e.g. Division dVS and dVise, Sense8 World Tool Kit WTK) The increased power of parallel processing is essential to meet timing constraints in real applications [95] and for this reason high end graphics systems are network parallel or MP parallel [4, 33, 20, 75, 81]. No system to date, however, incorporates appropriate support to time critical graphics and low latency synchronization schemes [96, 91] In addition to generic support systems, a variety of software tools exist to solve specific problems. Examples are domain specific toolkits for supporting ....
