Form

    Form is a three-dimensional object with volume of height, width and depth. These objects include cubes, spheres and cylinders. Form is often used when referring to physical works of art, like sculptures, as form is connected most closely with three-dimensional works.

Organic

Geometric

     When a shape acquires depth and becomes three-dimensional, then it takes on form. For example a circle is a shape. Corresponding forms can be cylinders and spheres. A triangle is a shape which can be a pyramid as a form. In addition to geometric forms, there can also be amorphous forms.
