Have you ever walked down the street and been blown away by a billboard that looked so realistic it seemed like it was popping out of the wall? Well, my friend, I hate to break it to you, but it's all a big, fat lie. That's right, those 3D billboards and building illusions you see are nothing more than a clever use of force perspective.

Force perspective is an age-old technique that artists and architects have been using for centuries to create the illusion of depth and dimensionality in their work. It works by manipulating the scale and position of objects in relation to the viewer's line of sight. By making objects appear larger or smaller than they actually are, and positioning them at certain angles, it creates the illusion that they are closer or further away from the viewer than they really are.

So, how does this translate to advertising? Well, it turns out that force perspective is a popular tool for advertisers looking to create eye-catching 3D billboards and building illusions. By using computer programs like Photoshop and Illustrator designers can create images that appear to be 3D when viewed from a certain angle. They do this by carefully manipulating the perspective of each element in the image, making some appear larger or smaller than they actually are, and positioning them in such a way that they appear to be popping out of the wall. The use of 3d packages like Blender and Nuke have made it so that designers can create more elaborate animated designs that can then be flattened and displayed in real life.

Of course, the illusion only works if you're standing in the right spot. If you move too far to the left or right, the illusion falls apart and you're left staring at a flat, 2D image. But from the right angle, it can be truly impressive. And let's be honest, who hasn't stopped in their tracks to take a closer look at one of these 3D billboards?

The use of force perspective in advertising dates back to the 1800s, when advertisers would paint images on the sides of buildings to promote their products. In the early 20th century, advancements in printing technology allowed for more elaborate and detailed billboards, and the use of force perspective became more widespread. Today, with the advent of digital design tools, the possibilities are virtually endless.

So, the next time you're admiring a 3D billboard or building illusion, remember that it's all smoke and mirrors (well, not literally smoke and mirrors, but you get the idea). But hey, there's no harm in enjoying the illusion, right? After all, advertising is all about grabbing your attention and making you remember a product, and these 3D billboards certainly do that. Just don't try to walk through the wall, okay?
