Francis Ching's Form

Primary Solids:

Primary shapes can be extended or rotated to generate volumetric forms or solids that are distinct, regular, and easily recognizable. For example, circles can generate spheres and cylinders and squares can generate cubes. With this context in mind, the word "solid" does not refer to firmness of substance but rather to a three-dimensional geometric body or figure.

Dimensional Transformation:

A form can be transformed by altering one or more of its dimensions and still retain its identity as a member of family of forms. A cube, for example, can be transformed into similar forms through discrete changes in height, width, or length. The cube can be compressed into a planar form or be stretched out into a linear one.

Subtractive Forms:

When regular forms have fragments missing from their volumes, they retain their formal identities if we perceive them as incomplete wholes. We refer to these mutilated forms as subtractive forms. Because they are easily recognizable, primary solids adapt readily to subtractive treatment. These forms will retain their formal identities if portions of their volumes are removed without deteriorating their edges, corners, and overall profile.

Clustered Form:

While a centralized organization has a strong geometric basis for the ordering of its forms, a clustered organization groups its forms according to functional requirements of size, shape, or proximity. A clustered organization is flexible enough to incorporate forms of various shapes, sizes, and orientations into its structure.

Surface Articulation:

Our perception of the shape, size, scale, proportion, and visual weight of a plane is influenced by its surface properties as well as its visual context. A distinct contrast between the surface color of a plane and that of the surrounding field can clarify its shape, while modifying its tonal value can either increase or decrease its visual weight.
