    A few examples of shape are the triangular shape of modern jet aircraft and the shape of a common single-family dwelling. Humans have modified the landscape in very interesting ways that has given shape to many objects, but nature also shapes the landscape in its own ways.

  3. Vanishing point - Wikipedia

    en.wikipedia.org/wiki/Vanishing_point

    For example, when α is the ground plane and β is the horizon plane, then the vanishing line of α is the horizon line β ∩ π. To put it simply, the vanishing line of some plane, say α , is obtained by the intersection of the image plane with another plane, say β , parallel to the plane of interest ( α ), passing through the camera center.

  4. Shape and form (visual arts) - Wikipedia

    en.wikipedia.org/wiki/Shape_and_form_(visual_arts)

    In the visual arts, shape is a flat, enclosed area of an artwork created through lines, textures, or colours, or an area enclosed by other shapes, such as triangles, circles, and squares. [1] Likewise, a form can refer to a three-dimensional composition or object within a three-dimensional composition.

    It can also be looked at as art form, which can be expressed through fine art. A form encloses volume, has length, width, and height, unlike a shape, which is only two-dimensional. Forms that are mathematical, a sphere, pyramid, cube, cylinder, and cone, are known as geometric forms. Organic forms are typically irregular and asymmetrical.

  6. Picture plane - Wikipedia

    en.wikipedia.org/wiki/Picture_plane

    In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work.

  7. Photogrammetry - Wikipedia

    en.wikipedia.org/wiki/Photogrammetry

    Low altitude aerial photograph for use in photogrammetry. Location: Three Arch Bay, Laguna Beach, California. Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.

  8. Distortion (optics) - Wikipedia

    en.wikipedia.org/wiki/Distortion_(optics)

    In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...

  9. Image geometry correction - Wikipedia

    en.wikipedia.org/wiki/Image_geometry_correction

    The simplest application of image geometry correction is a specific case known as keystone distortion correction derived from Keystone effect.Keystone distortion gets its name from the symmetric trapezoidal distortion resulting from misaligned projector placement in the vertical dimension (although the term is generally applied to the non-symmetric quadrilateral shape that occurs from an off ...
