  2. Vanishing point - Wikipedia

    en.wikipedia.org/wiki/Vanishing_point

    The vanishing point may also be referred to as the "direction point", as lines having the same directional vector, say D, will have the same vanishing point. Mathematically, let q ≡ ( x , y , f ) be a point lying on the image plane, where f is the focal length (of the camera associated with the image), and let v q ≡ ( ⁠ x / h ⁠ , ⁠ y ...

  3. Perspective (graphical) - Wikipedia

    en.wikipedia.org/wiki/Perspective_(graphical)

    How linear or point-projection prospective works: Rays of light travel from the object (cube), through the picture plane, and to the viewer's eye (O). Vanishing points emitting straightly lines coincident with the edges the cube drawn on the picture plane are located at the left and right of the plane.

  4. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    its vanishing point, found at the intersection between the parallel line from the eye point and the picture plane. The principal vanishing point is the vanishing point of all horizontal lines perpendicular to the picture plane. The vanishing points of all horizontal lines lie on the horizon line. If, as is often the case, the picture plane is ...

  5. Picture plane - Wikipedia

    en.wikipedia.org/wiki/Picture_plane

    The horizon frequently features vanishing points of lines appearing parallel in the foreground. The technique for creating a basic two-point perspective drawing, including the sight rays, the picture plane, the left and right vanishing point construction lines, the horizon line, and the ground line

  6. Reverse perspective - Wikipedia

    en.wikipedia.org/wiki/Reverse_perspective

    Technically, the vanishing points are placed outside the painting with the illusion that they are "in front of" the painting. The name Byzantine perspective comes from the use of this perspective in Byzantine and Russian Orthodox icons ; it is also found in the art of many pre-Renaissance cultures, and was sometimes used in Cubism and other ...

  7. Curvilinear perspective - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_perspective

    Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).

    For those who are feeling “stuck" or overwhelmed while striving for work-life balance, some experts recommend adopting a “pendulum lifestyle." Psychologists weigh in on the potential benefits.

  9. Oblique projection - Wikipedia

    en.wikipedia.org/wiki/Oblique_projection

    In cavalier projection (sometimes cavalier perspective or high view point) a point of the object is represented by three coordinates, x, y and z. On the drawing, it is represented by only two coordinates, x″ and y″ .
