=== 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 the illusion of depth.
