## SEAN CASSIDY

AUTHOR ILLUSTRATOR   One point perspective Lesson 3 In this lesson, we’ll use the same three rules of one point perspective in order to make the room larger and more interesting. Let’s put a step in the floor of this room. A natural place for the   step would be in line with the step that we have just   created in the wall.   1.  Extend “LINE A” so that it goes across the room   until it meets the wall on the left.   This line will be the top of the step. 2.  We’ll draw the rest of the rectangle below this line. At each   end of the whole line, draw two vertical lines of equal length.   If we make these vertical lines short, then we’ll have a regular   step. If we make them long, then we’ll have a small wall.   I’m going to make a normal step.  (Later, I'll make a higher   step so you can see what it looks like.)   3. Join the lower ends of those lines with a horizontal line. 4.  Let’s finish things by drawing the two new floor lines. (Remember, these must point at the VP.) Next, we’ll erase those lines which no longer make sense. Erase “Line A”.  Erase the old floor lines. 5.  Congratulations! Your room looks much better than a plain box. If you had drawn a rectangle a lot higher than a normal step, you could have ended up with something like this.   In the next lesson, we’ll break the rules.   Go back to Lessons Page   Go to Lesson 4
