+// 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.
