To let the user look up or look down, use the ALT key with the UP or DOWN arrow keys. Wand Tracking and Interaction Wand movement is controlled by combining mouse movement with keyboard keys. To move the wand left, right, forward, or back, hold down the CTRL key and move the mouse left, right, up, or down. Hold down the ALT key and move the mouse to rotate the wand around the vertical or horizontal axes. Interprocess Communication CAVE Library programs are a collection of processes - at least one rendering process, an application or compute process, and a tracker process.
Shared memory is used to communicate among the process set.
To experiment with using the CAVE Library's shared memory support to communicate between the application process and the rendering process, complete the Lab Exercise Interprocess Communication . This Lab Exercise uses a button on the wand to switch between two ways of drawing a molecule. The program intially draws all the molecule's atoms. By default, the CAVE coordinate system is a 10'-cube, with the origin at the physical center of the floor. The origin for the ImmersaDesk is positioned similarly.
