Spatial logic allows humans to mentally visualize three dimensionally what is represented two dimensionally. Objects and their representations can be misaligned through means of projection or perceptive errors related to optical illusions or lack of depth perception cues. Three dimensional forms produce two dimensional reproductions not solely through representation, but in the creation of shadows. When light interacts with an object, its shadow creates a compressed spatial condition.
Various conditions can be created from one object as lighting angles change to form new shadows. Shadows portray a projected version of a form, similar to architectural drawing conventions flattening forms.
