Step 1 Begin with a simple room (just like last time) Draw a flat door.
Step 2 Instead of adding a little bit of depth to your door, extend the horizontal lines until they reach the outer vertical line of your door. Now it looks as though the door extends even further into the wall. Erase the bottom orthogonal to make it look as though the floor extends back into the space.
Step 3 To make it look like a hallway intersects, draw two vertical lines from the floor to the ceiling. Just like you did with your door, draw two horizontal lines that extend to the outer vertical line. Erase the bottom and the top orthogonals this time to extend the floor and the ceiling back into the space.
Step 4 Start with a simple rectangle coming out of the wall, just like you did with the small rectangle last time. This time, make sure it is taller than your vanishing point.
Step 5 Draw the top and bottom orthogona ls to create a flat front. Connect them with a vertical line.
Step 6 To divide the front face in half, draw an “X”. At the intersection, draw a vertical line. This divides the space in half. After you have drawn your vertical line, erase the “X”
Step 7 Repeat this process again, only this time divide the two halves. This creates four spaces. Erase the two “X”s.
Step 8 Continue to divide the spaces until you basically can’t divide them anymore. Continue erasing the “X”s after each vertical line is drawn. If you don’t do this, it will look like one big jumbled mess.
Step 9 Divide the top half from the bottom half by finding middle of the height of your lockers (you can just eyeball it) and drawing an orthogonal right through. Now move to the back wall. First divide the space in half. Then divide the halves in half. Then divide the quarters in half. Then divide the eighths in half.
Step 10 Draw orthogonals from each of your points. Now it looks like you have a bowling lane on your ceiling. Wouldn’t that be sweet if you did?
Step 11 To correctly space the ceiling tiles apart, draw a diagonal line (not in perspective) from one corner to the other. See how I did it in the picture? Make sure it’s drawn in lightly. Next, at each intersection of the diagonal line and orthogonal, you will draw a horizontal line. When you are finished, erase the diagonal line.
Step 12 Now what if you want to have a hallway that is partially hidden behind your lockers? Draw the vertical lines like before, except this time, have one stop at the top of the lockers. Erase the bottom and top orthogonals and voilà!, you now have a hallway that is hidden behind the front of the lockers. Now that looks awesome!
Step 13 Now suppose your hallway doesn’t end at a flat wall. What if it extends back to the right and left? Erase the bottom horizontal line and just move it up a bit. Do the same to the top, except you’ll be moving it down a bit. Make sure you continue the ceiling tiles too! Now it looks like someone can walk down the hallway and turn to the right or left and continue on their journey.
…and that’s it! Congratulations! Your drawing looks awesome! You can now start combining what you learned the first time with what you have just learned. Remember, you can still combine/alter/manipulate all of these shapes/objects and create any number of things. The possibilities are endless! Go forth, young grasshopper. Make art!
