2. Defining Perspective • First studies of linear perspective attributed to Leon Battista Aberti and sculptor Filippo Brunelleschi in the 15th century. They demonstrated that space could be articulated mathematically to express depth • Perspective mimics the way the eye sees space and objects in space. • Linear and intuitive perspective; drawing perspective “by eye” without using geometric rules. • Aerial perspective: the effect produced by diffusion of light in the atmosphere whereby more distant objects have less clarity of outline and are lighter in tone.

3. Linear vs. Intuitive

4. What is Linear Perspective?A form of perspective in drawing and painting in which parallel lines are represented as converging so as to give the illusion of depth and distance • One Point Perspective: a single vanishing point • Two Point Perspective: two vanishing points • Three Point Perspective: three vanishing points • Multiple Point Perspective: multiple vanishing points

10. Definitions • Vanishing Point is the imaginary point on the horizon line where lines converge • Horizon Line (or Eye level) is the imaginary line located at eye level from the position of the viewer and changes according to the position of the viewer. • Converging Lines are diagonal lines that move away from the viewer to the vanishing point creating depth and distance. • Parallel Lines are lines that run parallel to the horizon line • Line of Sight the position of the viewer peering through and at the picture plane. • Perspective Center determines that objectives as they move closer to the vanishing point become shorter in length/width to describe their distance ( a form of foreshortening)
