=== Three-dimensional images ===
Aside from sculpture and other physical activities that can create three-dimensional images from solid material, some modern techniques, such as [[holography]], can create three-dimensional images that are reproducible but intangible to human touch. Some photographic processes can now render the illusion of depth in an otherwise "flat" image, but "3-D photography" ([[stereoscopy]]) or "[[3D film|3-D film]]" are [[optical illusion]]s that require special devices such as eyeglasses to create that illusion of depth.

Copies of 3-dimensional images have traditionally had to be crafted one at a time, usually by an individual or team of [[artisan]]s.  In the modern age, the development of [[plastic]]s and other technologies made it possible to create multiple copies of a 3-dimensional object with less effort; the advent and development of "[[3D printing|3-D printing]]" have expanded that capability.
