first example - first divide the floor into 16 squares

make some basic observations about the ref - what are the main objects in the scene

• approximate ratio of objects

• there are 2 characters

• the adult is about 2x height of the kid

  

  bottom right example - use 1 of the 16 blocks to draw 1 of the objects in the scene

  

  knowing the width of the block we made - use that to approximate the ratio of the sink next to it

  • krenz guess 1 → 1.5

  

  could even use the multiply method to check more thoroughly - could be 1.5 → 2

  

  end of the bench still has 1 section - lets call it 1

  

  

  relay info back to your sketch

  

  repeat for rest of the major furnitures

  

  next guess the height for the initial furniture (this might be out of order) - 1.5 → 2

  

  Note - height of a normal room is around 2.75 → 3 metres

  Note - height of a normal table is around 80cm → 90cm (about to your waist, so half of 1.7m)

  assuming the table is 80cm, and normal height of roof indoors is 2.7m, we'll need to draw about 3.5 of these cabinets to get the height of the roof

  

  process recap

  create the floor, box it

  add 1 furniture

  

  find the roof based off this furniture

  

  next draw any human characters

  

  after understanding all the relationships + ratios of the main objects, you can then rotate the scene as you like and draw it (like in week 1)

  

  Human Figure in Perspective

  when drawing the left example - what you're actually practicing is the ability to draw body ratio (head → chest → limbs)

  

  to actually grasp spatial relationship you need to break the body down and draw it in reverse

  

  draw the body in side/top view and break down the ratios in terms of actual numbers

  

  because of this particular angle (45 degrees), the angles are quite linear, so you can judge some of the distances by eye (this example is 5 units high)

  

  construct the edges of the box - using pen tool to check angles and inserting (middle edges) to average out the angle

  

  note - you don't have to be super accurate about the numbers, this is only for demonstrating the concept

  creating the slanted edge

  

  using another box as example

  

  looking at the side view below, can see his entire back runs along that slanted edge

  

  imagining the kneecap as a ball, we can see it runs up along the front edge, to 2 units high

  

  using heel = sphere, it lines up against the back of the box

  

  draw crotch area on the cylinder, calculating the origin point of the other leg

  • using other feet calculate the bottom edges of the box

  

  

  2 units back

  

  can hide the first leg to draw the second

  

  using side view to determine where the kneecap is above on the grid

  

  

  

  similar method to find the elbows

  • look at the side view, how high is it, where is it along the x axis of the grid?

    

  use same method to draw the wrist + hand

  • the other arm is another example

  

  if the arm moves in another axis, not just y, you just do the same, but now using the front diagram to see how far in terms of grid space it moves

  

  say it moves the other direction

  

  use comparisons to find out the other arm - its in the same axis as the knee of the stretched out leg

  

  note - you don't necessarily need the top down diagram, but you definitely need side and front view

  imagine bodies as cubes/ erasers

  

  put on grid, draw a line to help you draw the body's curve later

  

  draw eraser
