How much space fits into a painting?

Throughout the History of Art, painting, understood as a two-dimensional surface, has been presented as a window to the world and real space. One system of representation in technical drawing is dihedral projection, in which three views of an object (plan, elevation, and section) are drawn, allowing us to understand the form and the space it occupies in relation to other objects.

The series of mobile panels in Sequence of Dihedrals, by Sergio Prego, reveal this Basque artist’s study of the transformation of an object and the space around it through the slight movement of its planes.
