Abstract

The invention relates to a system for obtaining the two basic images which make it possible to produce a three-dimensional effect, for any computerised application handling three-dimensional views or objects, without modifying this application. With reference to Figure 1, the device includes two work stations (1) and (2), linked in order to share data (3). Their input units (4) (5) are linked by a module (7) and their outputs (8) (9) generate the three-dimensional image via a display (6) which receives them.

Description

DESCRIPTION
The present invention relates to a system for obtaining the two basic images which make it possible to produce a three-dimensional effect, by binocular vision, of any graphic computer application, dealing with an object described in three dimensions, without modifying this application.

These computer applications <eg Computer Aided Design ... etc) are currently not viewable other than on a binary screen. This is a hindrance to the current object manipulation described in all three dimensions (height, width and depth, for example).

The ability to design or modify specifically each application to cover this need would be prohibitively expensive compared to the system according to the invention which is independent of any existing and usable for all applications.

The present invention comprises two workstations traditionally used
<half-cro-computer, workstation ...) having their input peripherals linked by a coupling module that initializes and synchronizes the operating mode of the device. These two stations share the same data via a link (for example of the local or serial network type). In addition, the two screens, in particular the output members of the display signal or signals, have a bypass which constitutes the two output images of the device and which, after the initialization phase, are able to serve as input to any three-dimensional visualization system (in particular the binocular vision covered by the invention patent pcnuaeooos)
According to particular embodiments - The coupling module can be electronic at the cable level.

- The coupling module can be mechanical at the mouse or keyboard.

 The coupling module can be logical (computer code) on one or the other of the stations.

The coupling module may take into account new information related to the three-dimensional display apparatus.

 - The positioning device (mouse) can be completely replaced by a new device (glove, handle).

- The screens of the two stations can be simply replaced by the three-dimensional display device, this lowering the operating costs.

The accompanying drawings illustrate the invention
Figure 1 shows an embodiment of the device.

Figure 2 shows an alternative embodiment.

 With reference to these drawings, the device comprises two work stations (1) and (2) connected to share data (3). Their input members (4) (5) are connected by a module (7) and their outputs (8) (9) generate the three-dimensional image via a display (6) which receives them.

 Lemodule (7) is such that it allows the functions necessary for the system according to the invention, in particular the initialization which unitarily adjusts the view (10) then lavue (11) so that the subsets of the application which stand out three dimensions are net, then it synchronizes the entries in respect of the functions of the application.

In the embodiment of FIG. 2, a member specific to the three-dimensional environment (12), for example a handle or a glove or a six-axis sensor, replaces or supplements the initial positioner such as the mouse or the digitizing table. It also appears that the output is direct to the three - dimensional display as mentioned in one of the particular modes.

According to a variant not illustrated, an organ such as a six-space ball ("space ball") allowing six degrees of freedom in input and having function keys could be the support of the module (7) with a remote processing logic on one or both positions.

The device according to the invention is particularly intended for the three-dimensional display of existing applications and to enhance their use by a better ergonomics of the depth of the objects and data determined in a three-dimensional space.
