Define Vanishing Point In Perspective Drawing. In drawing vanishing points are the points at which lines appear to converge. This is the standard receding railroad tracks phenomenon.
The easiest way to see this is to consider a pair of points on two parallel lines that travel together away from the drawing plane. This is the standard receding railroad tracks phenomenon. If the parallel lines are not parallel with the drawing plane then their image on the drawing plane passes through a fixed point called the vanishing point.
It is a fundamental concept of composition and perspective drawing.
Using the example of a straight road clearly illustrates what this means. This video shows you how locate the vanishing points for an object in two point perspective. A good example of this is when you draw a cube from the view of its corner. Vanishing points are created because of the fact that as things move further away from our eyes they appear smaller.
