STEPS

assignment

final drawing

Create 3-D forms on a grid plane.

Apply color values to support the illusion of space.

1. grid

grid step 1

Grid dimensions: 15 x 15 squares

Draw the front side of the grid and divide it into 15 segments.

Connect each marks on the line with the vanishing point.

grid step 2

Complete the grid using the "checkerboard" method.

2. planning

grid layout

These are the shapes that you need to build in 1-point perspective

grid step 3

Position the shapes on the grid.

You can shade them or outline lightly.

3. building forms

Build one form at a time.

box in perspective

Draw vertical lines from each shape's corner

Define the height of the form (you decide on the height)

Remember:

  • All vertical lines stay vertical
  • All horizontal lines stay horizontal
  • All lines, that show depth - go to the vanishing point
  • Draw all lines (corners) even if they are not visible
block in perspective

Make a rectangular cutout into the biggest form (as shown).

constructing a cutout:

cutout in perspective

Start with a simple block form.

If you placed it in the center of the grid - you will have two sides visible: the front and the top.

Remember: the front side is where you do all extra measurements and form changes.

Draw a cut-out on the front of the block.

Connect all new corners to the vanishing point

Where the back top corner line crosses the new receding lines - draw two vertical lines down to the other two receding lines.

Connect the two points with a horizontal line.

The new form is done.

Now you can erase the construction lines.

Continue with the rest of the forms.

1 point perspective form 3

Outline all visible corners.

Color the forms using a variety of color values - keep the values consistent.
