- // Set the TrackerBaseToImagePlate transforms for these screens. This
- // transforms points in tracker base coordinates to each screen's image plate
- // coordinates, where the origin of the image plate is defined to be the lower
- // left corner of the screen with X increasing to the right, Y increasing to
- // the top, and Z increasing away from the screen.
- //
- // Without head or sensor tracking the tracker base is still needed as a fixed
- // frame of reference for describing the orientation and position of each
- // screen to the others. The coexistence to tracker base transform is set to
- // identity by default, so the tracker base origin and orientation will also
- // set the origin and orientation of coexistence coordinates in the physical
- // world.
- //
- // The tracker base and center of coexistence is set here to the middle of the
- // edge shared by the two screens.

- // Sometimes it is desirable to include the bevels in between the monitors in
- // the TrackerBaseToImagePlate transforms, so that the abutting bevels obscure
- // the view of the virtual world instead of stretching it out between the
- // monitors. For a bevel width of 4.5 cm on each monitor, the above commands
- // would become the following:
- //
- // (ScreenAttribute left TrackerBaseToImagePlate
- // (Translate 0.405 0.144 0.0))
- // (ScreenAttribute right TrackerBaseToImagePlate
- // (Translate -0.045 0.144 0.0))
- //
- // Conversely, a similar technique may be used to include overlap between the
- // screens. This is useful for projection systems which use edge blending
- // to provide seamless integration between screens.
-
-
- // Create a view using the defined screens.

- // Set the eyepoint relative to coexistence coordinates. Here it is set 45cm
- // toward the user along Z, extending out from the midpoint of the edge shared
- // by the two screens. This will create the appropriate skewed projection
- // frustums for each image plate.
- //
- // If a planar display surface is all that is required, the same effect could
- // be achieved in a virtual screen enviroment such as Xinerama by simply
- // creating a canvas that spans both screens. In some display environments the
- // use of a canvas that spans multiple physical screens may cause significant
- // performance degradation, however.
- //
- // See j3d1x2-rot30 for an example of a non-planar configuration that cannot be
- // achieved through a single canvas spanning both screens.
