 {{:cave_hardware_config:all:dimensions.jpeg?600|}}
+===== Notes =====
+  * The ceiling and the floor have different depths (floor: 87.50" and ceiling: 82.25")
+  * The floor has a 7.85" blend zone per projector.  The last 7.85" of FLOOR_LEFT, and the first 7.85" FLOOR_RIGHT is in the blend zone and should be the same pixels.
+  * The **origin** of the CAVE within Vizard is the origin of Dtrack, which is located in the middle of the floor at the farthest point from the front wall.  All points used to define the rest of the CAVE are based on that point.  Vizard uses meters for units, regardless of the units that Dtrack uses.
+  * Vizard requires calculating the distance between the origin and the two bottom corners of the front wall.  This is called **originLeft** and **originRight** in its configuration file.
+  * The **origin** of the CAVE within getReal (and CAVELib) is in the middle of the floor, up against the front wall.  You specify within getReal the units, ours is defined in inches.
