This document discusses one-point and two-point perspective techniques in art. One-point perspective uses a single vanishing point to draw lines converging to create the illusion of depth. Two-point perspective uses two vanishing points, with lines drawn from shapes to each point. The document provides step-by-step instructions for creating basic one-point and two-point perspective drawings, explaining how to place shapes, draw orthogonal lines to vanishing points, and add parallel lines and shading to depict three-dimensional forms.
