Perspective

Linear perspective is a way to create an illusion mathematically on a flat surface to show distance in objects and showing the shape of the object to give it a 3D effect.

Horizon Line: A line drawn across the canvas to show the eye level of the viewer. It shows where the ground and sky meet.

Vanishing Point: The point in the art work where all the lines appear to be joining together in one sport at the horizon line. The vanishing point is mainly at the viewer’s eye level.

Orthogonal Lines: Diagonal lines that are straight and meet to connect points around the edges in the picture to the vanishing point. It helps the viewer to see the depth of the picture.

Transversal Lines: The side lines of the orthogonal lines that lead to the vanishing point of the picture.

One point perspective: Single vanishing points to show an object

Two point perspective: There are two points where the lines of the shape will lead to instead of one.

While Leonardo was looking at depth perception, he began adding the correct shadowing in the right places. He was also very good at showing the blue atmosphere in the background to show depth in the picture. He also changed the size of far off objects as another way to show the depth in the background.

Atmospheric/ariel perspective is the distance shown on something because of the atmosphere and the fading out of colors. Leonardo thought that the because of the moisture and dust in the air was causing far off things to appear blue and hazy. The light from the sky would reflect onto the landscape of objects causing the color to be blurred out and appear blue.

The perspective of a circle is called an eclipse and it is controlled by a rectangle shape.
