2. TWO POINT PERSPECTIVE

           This type of perspective is also known as "oblique perspective". Now there are two vanishing points
           on the horizon line (normally on either side of the page/block/picture). Only the vertical lines remain
           straight up and parallel. All horizontal lines now became converging lines too. This is the most popular
           type of perspective as the illusion of volume is created. Here the object is usually viewed at an angle
           to the picture plane.


           Procedure:
            1.  Draw the horizon line.
            2.  Draw in two vanishing points on either side of the page on the horizon line.
            3.  Draw one vertical line (the side of a box), anywhere below the horizon line.
            4.  Connect the top and bottom of this line to each of the vanishing points.
            5.  Now with vertical lines cut the box off on the two sides.
            6.  Where these vertical lines touch the converging lines draw a converging line to the opposite
               vanishing point.
            7.  To make it transparent... join the bottom side
               corners to the opposite vanishing points. Draw a                   GOOD
               vertical line from the bottom cross of converging                 LUCK TO
               lines to where the top converging lines cross.                      YOU!

           Homework: Draw any two of the following...
               1. Draw a suitcase.
               2. Draw two dice next to one another.
               3. Draw a street corner with buildings and roads.


           3. THREE POINT PERSPECTIVE
           This type is often referred to as "aerial perspective" and is widely use in the commercial art world. We
           now have three vanishing points and now there are no vertical, horizontal or parallel lines. All lines
           converge at a vanishing point. Two vanishing points are on the horizon line while the other departs
           from the general rule and is nowhere near the horizon line.


           Procedure:
               1.  Draw the horizon line.
               2.  Draw in two vanishing points on either side of the page on the horizon line.
               3.  Draw another vanishing point anywhere below the horizon line - normally near the centre
                   between the other two vanishing points.
               4.  Draw one vertical line (the side of a box), anywhere below the horizon line, yet it must
                   converge towards the bottom VP.
               5.  Connect the top and bottom of this line to each of the top vanishing points.
               6.  Now with vertical lines cut the box off on the two sides, yet they must converge towards the
                   bottom VP.
               7.  Where these vertical lines touch the converging lines draw a converging line to the opposite
                   top vanishing point.
               8.  To make it transparent... join the bottom side comers to the opposite vanishing points. Draw a
                   vertical line from the bottom cross of converging lines to where the top converging lines crass,
                   yet it must converge towards the bottom VP.
           Homework:
               1. Draw three boxes, of different lengths and sizes, using aerial perspective.
