This is important when// precise scaling between objects in the virtual world and their projections// into the physical world is desired through use of explicit ScreenScale view// attributes. The defaults are 0.365 meters for width and 0.292 meters for// height.// (ScreenProperty topleft PhysicalScreenWidth 0.912)(ScreenProperty topleft PhysicalScreenHeight 0.680)(ScreenProperty topright PhysicalScreenWidth 0.912)(ScreenProperty topright PhysicalScreenHeight 0.680)(ScreenProperty bottomleft PhysicalScreenWidth 0.912)(ScreenProperty bottomleft PhysicalScreenHeight 0.685)(ScreenProperty bottomright PhysicalScreenWidth 0.912)(ScreenProperty bottomright PhysicalScreenHeight 0.685)// Specify full screen windows.//(ScreenProperty topleft WindowSize NoBorderFullScreen)(ScreenProperty topright WindowSize NoBorderFullScreen)(ScreenProperty bottomleft WindowSize NoBorderFullScreen)(ScreenProperty bottomright WindowSize NoBorderFullScreen)// 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 point// 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 are set here to the center of the// 2x2 array with its basis vectors aligned to image plate coordinates.//(ScreenProperty topleft TrackerBaseToImagePlate (Translate 0.912 0.000 0.0))(ScreenProperty topright TrackerBaseToImagePlate (Translate 0.000 0.000 0.0))(ScreenProperty bottomleft TrackerBaseToImagePlate (Translate 0.912 0.685 0.0))(ScreenProperty bottomright TrackerBaseToImagePlate (Translate 0.000 0.685 0.0))// Create a view using the defined screens.// (NewView view0)(ViewProperty view0 Screen topleft)(ViewProperty view0 Screen topright)(ViewProperty view0 Screen bottomleft)(ViewProperty view0 Screen bottomright)// Set the screen scale.
