Single point uses the very basic technique of rendering the depth of three dimensional world on ২ dimensional surface such as paper. As discussed in the earlier tutorial, perspective drawing uses two main terminology. One is horizon line and other is vanishing point.
In case of single point perspective, there is one horizon line and one vanishing point. This is the simplest way of depicting the three dimensional world in two dimensional drawing surface. The idea behind the single point perspective is that distortion is rendered in only one axis.
Horizon line is chosen depending on the height of the observers eye level in respect to the frame being rendered. The point on the horizon line where everything would be so small that they would seem to disappear is the vanishing point.
Lets see the illustration -
One point to note that the vanishing point need not be in the middle of the horizon line. It defines the position of the observer with respect to the frame. A line perpendicular to horizontal line is also called line of sight.
Where should I place my horizon line?
Horizon line defines the eye level. So, the horizon line should be drawn high when the observer is viewing from a height and downwards. If the viewers eye level is close to the ground in comparison the overall scene then the horizon line should be drawn at a lower level in the frame.See the illustrations.
In the above image we have seen how the eye level of the observer moves the horizon line up or down. Now lets apply that on a sketch.
Where to place the vanishing point?
Centre? Yes possible. But not necessarily. It can be shifted from the centre towards right or left a little to void stiffness in the drawing. a little shift of the vanishing point from the centre should add a little dynamics in the scene. that being said, too much shifting shall distort the dimensions and managing the proportions may become difficult.
