3D window painting. At the beginning of the 15th century perspective drawing was invented in Italy to give paintings a more realistic view. The main observation in this was that the horizon is always at eye level from the viewer and that there are vanishing points. At some point painters wanted to make murals on walls and ceilings where the view point was not straight in front, but from an angle. This gave them the problem that images seemed distorted. For this they had to use the anamorphosis trick. ’Leonardo’s eye’ by Leonardo Da Vinci is one of the earliest examples in a study of anamorphosis. Standing on the view point you can best view a 3D painting with one eye to better fool your brain. Without depth perception the painting will better fit with the environment. For this reason a camera will register the illusion most perfect. he History of 3D Street Painting. Street painting is done on many surfaces and can be traced back to the renaissance era. In 1984, an artist named Kurt Wenner invented a new kind of pavementart. This form of art came to be known as anamorphic of 3Dpavement art. 3D printing is a process for making a physical object from a three-dimensional digital model, typically by laying down many successive thin layers of a material.
