Drawing tutorial 029 - Two point perspective

Vanishing points and single point perspective has  been discussed in earlier post. Single point perspective renders the three dimensional world on paper in a way that the object that are distant tends to vanish to one point which is called as vanishing point. Single point is good to describe scenes that has straight tracks like road or rail track that is tends to disappear in a distant horizon towards the line of sight.

However, for wide scene where the objects and elements in the frame are so far in both left and right of the viewer that they appear to vanish at a distance both side of the viewer it is necessary to apply two point perspective. This is useful while rendering objects like city view that spread both sides to long distances.

The concept is to apply to two vanishing points on two ends of the horizon line unlike one in the middle(somewhat) of the horizon line. The basis is illustrated in the sketch below.

While drawing a scene in two point perspective two things will count 1) The horizon line and 2) vanishing points. The vanishing points need not be on the frame being rendered on paper but it should be kept in mind where the imaginary vanishing point is and to draw all lines from the vanishing points only else the structures will look out of proportion. This may me thought as cropping the scene to area of interest only.

In the above sketch, the box with dashed lines is the area being rendered. The vanishing points are out of the box, but the lines coming out of the vanishing points are the guidelines for drawing the subject.
