- PERSPECTIVE FIVE - WESTERN RAILWAY
To create a perspective
grid using a single measurement and three vanishing points. This lesson
is to consolidate and further the notion of perspective 'scale'. That is,
as things of equal size recede they appear smaller. This time we will use
the CVP and a familiar and logical structure, a railway line.
The sketch pad,
HB pencil, ruler.
margin and title box then:
Construct the same light lines as in stage a, b, c, d, of the previous lesson until
we get the lines shown above.
This time we firm in the 'diagonals' which become railway line 'sleepers'.
Notice here we use a more simplified method of construction.
Keep adding sleepers.
After the student has completed the drawing to the stage above ask:
What shall we call the line that joins LVP, RVP and CVP? (answer 'horizon
How wide are railway tracks? (remember the old movies of people tied
to railway lines? - answer about 5feet).
If the distance between the sleepers is 5 feet what is the distance between
the second add fourth sleepers?
Add the extra light lines on the ground (two horizontal and three to the
CVP). We are going to build a station about 30mm (1,1/4") from track
Add the vertical lines 50mm (2") high and join to CVP
Firm in the lines as shown and ask:
How high is the building? The student should measure the width of the
tracks on the line directly opposite the front edge of the station and
apply that 'scale' to the building's height. Objects an equal distance
away from the 'observer' are subject to the same measurements of 'scale
' at that distance. In this drawing the scale is discovered by knowing
the width of the track at that distance.
Add the telegraph lines and poles and have the student determine their
height and distance apart.
up and print in the title as shown.
Encourage the advanced students to add three 12 foot cacti at various
locations in the landscape.
Complete the drawing adding a roof on the station, cactus, hills , train,
and birds etc.
