VEX & VOPS: PERSPECTIVE HALFTONE ILLUSION
Occasionally we find an E-Mail in our inbox that asks how to achieve a given effect. This time Jesper asked us how we’d go about creating something like this – spheres arranged in space to create the illusion of a halftone image when viewed from the right point.
What this illusion combines are two vintage techniques: Halftone rasterization and perspective projection.
Halftone rasterization is the process of breaking down a greyscale image into discrete dots of varying size in order to create the illusion of different brightness values when viewed from afar.
Forced perspective is a technique that’s been used as a practical effect in movies like “Close Encounters of The Third Kind” or “The Aviator” to make models appear bigger than they are. (It’s been abused all too often to seemingly hold the tower of Pisa as well.)
Also this article on Wired does a really great job at explaining how perspective and forced perspective works.
