Why do we see in the third dimension? How do anamorphic optical illusions work? In order to see a flat, painted object as three-dimensional, we have to trick our senses and our brains using various drawing and painting tricks and techniques. By first drawing subjects on textured surfaces and then adding paint using the drybrushing technique, you can create incredibly realistic 3D artwork. Cutting away excess paper adds to the effect, making it almost impossible to distinguish reality from illusion.
