3D Stereoscopic Cube
An interactive anaglyphic demonstration of depth through binocular disparity.
Parallel and Cross Eyed
A rotating trapezoid appears as a window swinging in perspective.
Red and blue appear at different depths.
A hole in the ground becomes a mountain when the picture is flipped.
Wick Deer - Full Version
Depth from Shading
Depth appears when shading gradients vary in figure and background.
Atmospheric haze tends to occlude distant objects; here, shaded objects appear farther away.
Odd arrangements of lines may have more structure than first appears.
A 3D mask appears to flip in depth when rotated.
Kinetic Depth Effect
Induced perception of depth from a rotating 3D object in two dimensions.
Sphere - Axial Rotation
Sphere - Rolling
A folded card whose depth flips much like a Necker cube.
Depth arising from monocular cues.
An unstable cube which flips in perspective.
Perception of depth based on varying contrast.
A change in apparent size with distance.
Black and White
Random Dot Stereogram
Depth perception elicited from displaced random noise.
Apparent depth induced by the motion of a shadow.
Rotating disks which elicit the appearance of depth.
Depth appears when Vasarely's 'Oervegn' is scaled asymmetrically.
