Grid drawing

Assignment

Create 3-D forms on a grid plane.

Apply color values to support the illusion of space.

1. Start with drawing a grid.

Grid dimensions: 9 x 9 squares

Draw 2 vanishing points on the horizin

Draw 2 receding lines to create the front corner of a grid.

2.Use ONE vanishing point at a time:

Using the "posts" method, divide the existing receding line into 9 segments (draw 10 posts). The posts can be any height.

3. Repeat the steps on the other side.

4. Erase all posts and other construction lines.

5. Connect all marks to the vanishing points,

Now you have the grid.

Planning

These are the shapes that you need to build in 2-point perspective.

6. Position the shapes on the grid.

7. You can shade them or outline lightly.

Building forms

Build one form at a time.

5. Draw vertical lines from each shape's corner

6. Define the height of the form (you decide on the height) - you do it by choosing the height of the FRONT CORNER of each form.

7. Remember:

All vertical lines stay vertical

The rest of the lines - show depth - they all go to one of the vanishing points.

Draw all lines (corners) even if they are not visible.

8. Keep the complex form to build the last.

Outline all visible sides and corners.

9. Continue with the rest of the forms.
10. Color the forms using a variety of color values - keep the values consistent.
