  2. Object diagram - Wikipedia

    en.wikipedia.org/wiki/Object_diagram

    "An object diagram is a graph of instances, including objects and data values. A static object diagram is an instance of a class diagram; it shows a snapshot of the detailed state of a system at a point in time. The use of object diagrams is fairly limited, namely to show examples of data structure."

  3. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    closer objects can block the view of more distant objects, but not vice versa; and; figures (i.e., foreground objects) tend to have convex borders. The study of visual illusions (cases when the inference process goes wrong) has yielded much insight into what sort of assumptions the visual system makes.

  4. Emission theory (vision) - Wikipedia

    en.wikipedia.org/wiki/Emission_theory_(vision)

    "Ptolemy’s ‘extramission’ theory of vision proposed scaling the angular size of objects using light rays that were emitted by the eyes and reflected back by objects. In practice some animals (bats, dolphins, whales, and even some birds and rodents) have evolved what is effectively an ‘extramission’ theory of audition to address this ...

  5. Visible spectrum - Wikipedia

    en.wikipedia.org/wiki/Visible_spectrum

    Visible-light spectroscopy is an important tool in astronomy (as is spectroscopy at other wavelengths), where scientists use it to analyze the properties of distant objects. Chemical elements and small molecules can be detected in astronomical objects by observing emission lines and absorption lines.

  6. Form perception - Wikipedia

    en.wikipedia.org/wiki/Form_perception

    Form perception is the recognition of visual elements of objects, specifically those to do with shapes, patterns and previously identified important characteristics. An object is perceived by the retina as a two-dimensional image, [1] but the image can vary for the same object in terms of the context with which it is viewed, the apparent size of the object, the angle from which it is viewed ...

  7. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    It helps to illustrate how 3D images "emerge" from the background from a second viewer's perspective. If the virtual 3D objects reconstructed by the autostereogram viewer's brain were real objects, a second viewer observing the scene from the side would see these objects floating in the air above the background image.

  8. Exploded-view drawing - Wikipedia

    en.wikipedia.org/wiki/Exploded-view_drawing

    An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

  9. Stereopsis - Wikipedia

    en.wikipedia.org/wiki/Stereopsis

    Other objects around the main object appear shifted in relation to the main object. In the following example, whereas the main object (dolphin) remains in the center of the two images in the two eyes, the cube is shifted to the right in the left eye's image and is shifted to the left when in the right eye's image.
