Grid in perspective

placing blocks

Assignment 1 - One-point perspective

Print out the grid.

Position a form on the grid.

Build up the form in 1-point perspective.

Placing a block

printable handout
block worksheet

Mark a 2x3 block on a grid - you can lightly shade it or outline the perimeter.

 

Building up

There are only 3 types of lines in one-point perspective (horizontal, vertical, and receding):

  • Horizontal lines (that are parallel to you picture plane and the front side of the grid) - stay horizontal
  • Vertical lines, that show height - stay vertical
  • Lines, that show depth - become receding lines and go to the vanishing point.

Add height to the block - draw a vertical line from each corner.

Defining the front side

What is the closest part of the shape? You always start with defining it first.

Define the front side of the block by placing the top corner line.

It should be horizontal and parallel to the bottom corner line.

Adding depth

Add depth by drawing two receding lines from the top two corners of the front side.

Finding the back side

Mark the crossing points of the receding lines and the back corners vertical lines.

These points define the height of the rest of the block: back, right, and left sides.

Completing the top side

Connect these two points.

If you've done everything correctly and accurately at this point - this line is a horizontal line (parallel to the front corner).

 

Done!

Apply the same steps to build more complex forms. If you get confused - break complex forms into simple blocks first.

L-shape

printable

Mark an L-shape on the grid.

Add height to your form.

Draw vertical lines from each corner (total of 6).

The layout and position of the shape can vary, but the steps stay the same.

Find the closest side of the shape. You are going to start with defining it first.

Connect the two vertical corner lines with a horizontal corner line - you decide on the height of it.

Add depth to the form by drawing two receding lines from its front top corners.

Note where these receding lines crossed the vertical corner lines.

Mark these points.

Draw a horizontal line from one of the points.

It is placed between the two vertical corner lines.

Now, that we have the right corner line defined - add depth by drawing a receding line from the top right corner to the vanishing point.

Note where the receding line crosses the back vertical corner line.

Mark that point.

Connect the two top back corners with a straight line to define the top side.

If everything is done correctly - this line is a horizontal line and is parallel to the front corner line.

Done!

Cross

printable

Start with marking a cross shape on the grid.

Add height by drawing 12 vertical corner lines from each corner.

What id the closest side?

Define its height.

Add depth by drawing two receding lines from the two top corners of the front side.

The top two receding lines are crossing the two vertical inside corners.

If you look at the shape layout on the grid - you will see that at these inside corners the top corner line should go horizontally.

Draw two segments of the top horizontal corner line.

Now we have a total of 5 sides done.

Add more depth by drawing two more receding lines on the left and right sides of the cross.

Note where these lines cross the far vertical corner lines.

Mark these points.

These points will define the height of these vertical lines.
Draw the next horizontal corner lines between the corresponding receding lines.

Add the last part of the depth.

Use existing receding lines that start at the very front top corners.

Mark the crossings.

These marks will define the height of the very back side of the cross.
Connect the two points with a straight line.
It should be a horizontal line.
Done!

Assignment 2 - Two-point perspective

Print out the grid.

Position a form on the grid.

Build up the form in 2-point perspective.

Block

Mark the perimeter of a rectangle on the grid.

There are only 2 types of lines in two-point perspective (vertical and receding):

  • Vertical lines, that show height - stay vertical
  • Lines, that show depth - become receding lines and go to one of the vanishing points.

Add height by drawing 4 vertical corner lines from each corner.

Front vertical corner:

Decide on the height of the block by marking the top front corner.

Draw 2 receding lines from that corner to the vanishing points.

Mark where they cross the right and left vertical corner lines. That will define the right and the left sides of the block.

From these two corner points - draw two receding lines to the vanishing points.

These two receding lines and the back corner line should cross at the same point. That will define the top side of the block.

Done!
