INKJET SCIENCE DEVICES
This section of the Project LITE web site contains links to PDF files of objects that can be printed with an inkjet or laser printer and then assembled. Each three dimensional model allows the observer to explore aspects of depth perception that cannot be fully probed using a two dimensional computer screen alone. |
Ames Room Demonstration The Ames Room presents the viewer with what appears to be a rectangular room with parallel walls and floor when viewed monocularly from one vantage point. |

|
Ames Trapezoidal Window When rotated slowly in one direction – and viewed either monocularly from a short distance or binocularly from a large distance – the window appears to oscillate rather than rotate around its axis. |
Hughes Sticking Out Room When viewed from a sufficiently large distance, either monocularly or binocularly, the parts of the painting that actually protrude appear to recede into the background of the scene portrayed. |

Ambiguous Corner Cube The Ambiguous Corner Cube can be seen to change between three equally plausible perceptual interpretations: a large cube with a smaller cube cut into it; a large cube with a smaller cube jutting out from it; and a large three sided "room" with a cube sitting in its back "corner." |

Ambiguous Tri-Wall The Ambiguous Tri-Wall has the property of having two equally plausible depth interpretations when viewed and analyzed by the human visual system. |
Ambiguous Tri-Wall Here two versions of the Ambiguous Tri-Wall are posted: the first is as above; the second is an undistorted tri-wall model. Hold and rotate one in each hand and compare their relative appearances and motions. |
|
Penrose Triangle The Penrose Triangle is an example of a class of two-dimensional figures that appears to be realizable in three dimensions, but is not. The version included here consists of essentially three orthogonal rods. When viewed from one direction and distance, it will look like the impossible triangle. |
