Communications of the rahan, P. Multiple users gather in a room and can experi- 3-D containers and communicate by message passing. Individual scenes are represented by their stage direct manipulation event. The larger the tribution mechanism. The following features make up the complete tracking pipeline: Figure 9 illustrates the use of this feature for the 3-D drag and drop of an application object across dis- play boundaries in a Studierstube environment com- Figure 8.

The slide sorter is the respective other host, which are also instances of the intended to resemble the traditional storyboard used in same kit class, but initialized to function as slaves. Another convenient feature of these properties are established in the desktop world, desktop applications is that many of them support a they are not studierstybe to it and are indeed useful to en- multiple document interface MDI —that is, working hance productivity in a 3-D work environment as well.
No limits to video resolution There are no limits to the size of input images except for memory consumption.
Studierstube also borrows elements from the desktop, such as multi- tasking and multi-windowing. For example, the current using a box instead of a rectangle seems to be the easiest paint color in an artistic spraying application can be set way of preserving the well-known properties of desktop individually by every user for every application object.
The Intergraph workstation was laborate with an existing Studierstube installation. This approach allows for several strategies regarding the arrangement of application ob- jects in the relevant locales. See examples 3 and 4 below.

This can be heterogeneous distributed infrastructure and is used in achieved by implementing the tracking system as a several research labs with studiwrstube variety of tracking devices loose ensemble of communicating processes.

The following features make up the complete tracking pipeline:. Yet there are other devices guarding such private information: More precisely, multiple displays can have independent points of view, but show images of an identical scene graph.
