ABSTRACT
A point, strictly speaking, has no dimension but marks a position in space. Quite often in the past points have been defined with a particular purpose such as to mark out territory, to assert ownership or dominion over an area, to act as landmarks, to provide a focus for a grand design, or merely to provide an interest in a featureless landscape. In the landscape, lines are very numerous and important. As natural lines they exist in stream patterns, tree trunks and branches, edges between vegetation types, the skyline or horizon, and rock strata. In the natural world, there are few perfectly flat planes. Regular, symmetrical crystalline surfaces are quite rare. In design terms the plane is often best understood as the medium for other treatment such as the application of texture or colour or as a device to enclose space.
