Perspective

Purpose:

To demonstrate and understand, learn & create, various perspective strategies to show depth on a two-dimensional surface;

To review and interpret some of the work created by Leonardo da Vinci.

Linear perspective is the illusion of depth and a third dimension on a 2 dimensional surface.

Horizon line: the line that separates ground from sky

Vanishing point: point were all parallel lines going into the distance converge on the horizon

Orthogonal lines: parallel lines that converge on the vanishing

Transversals: perpendicular lines to the horizon

One point perspective: The perspective with one vanishing point

Two point perspective: The perspective with two vanishing points

Objects further away appear smaller and less detailed than close objects.

Colors further away appear more dull than closer objects.

The further an object is, the more its color appears to be mixed with the color of the surrounding atmosphere. Da Vinci thought this was a result of water vapor and dust reflecting light away from objects in the distance, such as mountains.

Elliptical perspective: The circle is visualized on a grid of four squares. Then, the grid is distorted according to the perspective, and the circle is drawn on the distorted grid.
