One-Point Perspective projects teach how to show 3D attributes in 2D artworks by describing distance and depth.
Imagine you will be going on a road trip like me, Charlie the Stinkbug. Think about where you would like to go. Now, picture what you think you would see through the car window on that trip. What does it look like in that place? What things would you see that are special to only that place that you may not see anywhere else.
Here is a project where one-point perspective is used to draw a name in block letters. As you can see, the names are drawn in a way that shows depth and distance. You can see the letters as if they are not flat.
