Description:
A pretty rare technique in motion graphics, but commonly used in one or two areas such as projection mapping. What is happening here is an image is getting lined up so when it is seen from a specific angle it looks as it should do, but from any other angle it will just look like a mess because the perspective is completely off. You can see it in the Writing on the Wall music video from ok, as that whole music video is about forced perspective. The image may appear like it is lining up with the camera, but really the objects are further away. Really this is a great big illusion.
In projection mapping the content is rendered as if the camera is looking up at the building. So when it is projected back on the building, it lines up with the golden spot your audience views it from. If that is confusing, think how the tourist image would look in render, as it would not look like what is being projected on the building.
Fun fact on this one, Disney is very well known for their use of forced perspective throughout their theme parks. The Disney castle that sits in the middle of the park (for a very good reason) isn’t actually as big as it would appear. It is rather tall, but it is made to look taller than it actually is. As you go higher up the castle, the size of the windows are made smaller as if they’re further away, to make the building appear taller than it actually is.
Use: Use this when you want to create an illusion-like effect where the camera will come to a point and all of the parts of the image line up to make a new one.
