Vanishing Point Lines that are parallel to one another and level with the ground plane, such asfurrowsin a plowed field, appear to meet at the same point on the horizon line. This point is known as the vanishing point. The vanishing point is one of the most important points to establish accurately in order to…
The horizon is represented by the point at which the sea and sky, or flat land and sky meet. This is the natural and true horizon. Then true horizon line is always at the level of your eyes and will change as you change the elevation of view. The higher the elevation of view, the…
Every object appears different when viewed from various angles. In order to create a realistic illusion of the subject, we must view it and all other relating objects from the same viewing point. The viewing point can be seen as a straight line from our eye to the horizon line. If we move to the…
The “picture plane” is simply the surface area of the picture. The edges of the picture are the limits, or edges, of the picture plane. In the introduction we discussed how Alberti saw the “picture plane” as a window through which the artist sees the visible three-dimensional world. That window is the surface of our…
Subject We all know that the term “subject” refers to the object or scene that we are dealing with in the composition of our drawing or painting. It can be one item or many things, such as a complex scene from nature. Whichever it is, we must try and present that subject so as to…
This figure is similar to the previous one, except that the extremity A of the given line is raised from the ground, but the same demonstration applies to it. And now let us suppose the vertical plane K to be a sheet of glass, and the given line AE…
The conditions of linear perspective are somewhat rigid. In the first place, we are supposed to look at objects with one eye only; that is, the visual rays are drawn from a single point, and not from two. Of this we shall speak later on. Then again, the eye must be placed in a certain…
Perspective in the art of drawing and painting and in some relief sculpture is a technique that allows us to represent three dimensional objects and space on a flat surface or plane. This surface or planes is the board, paper, canvas, or surface onto which we draw or paint our impression and view of an…
