In The characterization shows a geometric function which is the linear placement the horizontal line and vanishing spotlight is used where the sky appears to meet the ground.
The painting I free-base to describe mathematical and geometric functions in art is The visual pyramid & Albertis open window
The geometric function shown in this painting is linear perspective. Alberti used the frequent knowledge of a visual pyramid to understand perspective. He described the visual pyramid as รข¦a figure of a body from whose base straight lines are pull upward, terminating in a single point. The base of this pyramid is a plane, which is seen. The sides of the pyramid are those rays, which I have called extrinsic.

The cuspid, that is the point of the pyramid, is hardened within the eye where the angle of the quantity This method is explain with an open window method
The painter/viewer is fit(p) at the peak of the pyramid. When looking from the peak through the pyramid, you can see lots of different planes cutting through the pick up plane. Some planes are parallel to the cutting edges, others are perpendicular, transversal, or horizontal. When projecting these lines on the image plane, you get the correct perspective projection. The perspective correct image comes into being by a linear projection from the base plane of the pyramid onto the image plane.If you want to get a full essay, order it on our website: Ordercustompaper.com
