We have all see these sidewalk and street images that appear to be 3D based on the viewers perspective, but then wildly distort when viewed from a different perspective.
Seems to me anamorphic distortion like this would be something Mathematica could do quite easily, but see only manual methods being used when searching the webs for instructions. Given that simple triangulated perspective would work, the variables would be viewing height, viewing distance and size of the actual chalk drawing. That would produce the triangle needed for distorting the perspective.
So for those variables the average US male is 5'9.5" and the viewing distance of 10 feet and the size of the projected image would be 20 feet tall.
Using the above normal perspective image image, how can Mathematica be used to create a distorted version that would view properly using the variables of viewer height, distance and viewing angle?
Here is an example done in Photoshop of the Captain America image that has been perspective distorted to appear correct when placed on the ground, by a person who's 5'10" and is 10 feet away
