Learning How To Draw

Elementary Perspective: Lesson 6 Room Inerior (CVP)
Time: Allow 60-80min - this is a double lesson - mark previous work
Aim: To create a perspective grid using a single measurement and three vanishing points but vanishing toward the CVP. We will also introduce the freehand method of constructing curves.
Materials:
  • 30x45cms or 12"x18" standard cartridge paper (thick, white, plain) sketchpad.
  • HB pencil
  • Ruler
Notes: Construct margin and title box then:

a) measure intervals of 24mm (1") along the base margin as shown and join to RVP

b) Where they cross the vertical line from CVP draw horizontal lines as shown above

c) add lines to CVP from marked intervals

d) extend and complete

e) shade alternate tiles

f) add two more rows to the outside

g) clean up with eraser if necessary

Revise ask:
What does RVP stand for?
What is the horizon?
How is it we can make a drawing with depth on a flat surface?

EXPLAIN :
The 'flat' surface is like a window or a sheet of glass. It is called a picture plane (PP). The 'observer', the person looking is standing a certain distance behind the PP and the floor is a particular distance in front of the PP.

At this point we interrupt our drawing to learn to draw circles - freehand. We need to know this to complete our project. So start a new sheet and ...
