In order to organize the world of Dream Grrrls and to increase computational performance the project has been splitted into single parts. Every part represents one of the dream worlds the user can explore.
Technically it is a number of CAVE programs to witch an rectangular area has been assigned. Those sub-programs are started up in dependence of the viewers position as computed by the head tracker. As the user crosses the border of a new world the sub-program will be started and run until the user steps out of the dedicated area.
