One point perspective allows objects and environments to be drawn so that at least one plane of the object or environment is perpendicular to the viewer's line of sight. Of the three perspective frameworks, it has the advantage of being the easiest to master and produces suitable interior perspectives for the communication of scale, portion and space.
The drawback with one point perspective is that it often provides static and uninteresting views of exterior environments. It is also difficult to clearly communicate the form of organically shaped products.
Two-line One Point Perspective
To assist you in learning how to drawing one point perspective consider setting up your drawing using a horizontal line to represent the horizontal vanishing line and a vertical line to represent the vertical vanishing line. Where these two lines intersect is the vanishing point to which both the vertical and horizontal planes will converge.
