Uses and types of perspective drawings

Naturally, distant objects appear smaller than their real sizes e.g. the stars, the sun, the moon etc. For instance, the farther we look down a long corridor in a building, the closer it appears to come. Perspective drawing therefore shows the pictorial representation of the apparent reduction in size of a distant object. Since architecture deals with large objects like buildings, perspective drawing becomes more useful in making architectural drawings realistic than either isometric or oblique drawing. Distant parts of a building are shown in perspective as tapering to a point, just as they appear to an observer of the actual building. Perspective projection can be in one point or two point perspective.

One point perspective: In this type of projection, the object is draws such that the edges are made to converge to a point called varnishing point.

Two-point perspective: in this case, there are two vanishing points. The object tends to tape in two directions, one to each vanishing point.
