The principles of perspective allow artists to draw objects so they accurately reflect their height, width, depth, and position relative to one another. In one-point perspective, all lines converge to a single point on the horizon. Two-point perspective addresses the drawing issues we face rendering our subject from the side, where horizontal lines converge to two points on the horizon. Two-point perspective is a critical skill for drawing from life, and creating your own imaginary 3D worlds from scratch.
