This document discusses the visual properties of form, including shape, size, color, texture, position, and orientation. It describes how these properties are affected by viewing conditions like perspective, distance, and lighting. Primary shapes like circles, triangles, and squares are examined for their symbolic meanings and stability. The transformation of forms is also summarized, looking at dimensional changes, subtraction, and addition of volumes. Different types of additive forms are defined, such as centralized, linear, radial, clustered, and grid organizations.
