To create nice background images, you might want to use the two point perspective technique. It's relatively easy to use and the results are very effective.
In this tutorial, you will learn to draw three different rectangles placed in three different locations. This will help you understand how to use this technique with ease!
First, draw a horizontal line to create the horizon. On this line, add two dots to form the vanishing points.
Next, draw three small vertical lines. Make sure that one of them is on the horizon line. We will build our rectangles from these three lines.
Start adding guidelines using your two vanishing points. I have used three different colors in this example to help you see how I did it.
Once this is done, add two vertical lines (one on each side) on each of the three shapes. You can place them at any distance you want. This will determine the sizes of your shapes.
Then, add a guideline (from your vanishing points) leading to each new lines you've just added. Notice that the shape in the middle doesn't require new lines in this step.
Finally, just draw the shapes using dark lines to complete the perspective effect.
That's it! Drawing nice shapes using this technique is pretty easy and straightforward! If you follow all steps carefully, it is almost impossible to make mistakes! I hope you had fun with this drawing lesson and good luck!
