Form is an element of art. It is the whole of a pieces visible elements and how they are displayed. The primary figures of form are extended 3 dimensional geometric shapes. In the diagram below of Maggies Dundee Building, in Tayside Scotland, the dominant form is a cone.
The IAC Building exemplifies Linear Form, which can result from a proportional change or from a series of repetitive elements.
In Formal Collision of Geometry, Edges and Corners are critical to the definition and clarity of form. The Frank Gehry ring and matching bangle from his jewelry line emphasize the forms joints.
