Definition and Outcome

A functional arrangement is created by several operations, dividing, merging, adding or subtracting. Typically, a larger volume is subdivided by surface or grid elements and then further refined by adding or subtracting of other volumetric elements.

All these operations (and the order of them) represent the definition data of the arrangement. The actual arrangement that is displayed in a canvas is the geometrical outcome of the definitions. A change of an arrangement is made by changing the definition or by changing the underlying elements that are referenced by the definition data. If a underlying surface, used as definition data in one or several arrangements, is changed then a new updated arrangement can be presented by a simple recreate operation.
