  2. Perspective (geometry) - Wikipedia

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

    Perspective (geometry) Two perspective triangles, with their perspective axis and center. Two figures in a plane are perspective from a point O, called the center of perspectivity, if the lines joining corresponding points of the figures all meet at O. Dually, the figures are said to be perspective from a line if the points of intersection of ...

  3. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane. 3D projections use the primary qualities of an object's basic ...

  4. Perspective (graphical) - Wikipedia

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

    Rays of light travel from the object, through the picture plane, and to the viewer's eye. This is the basis for graphical perspective. Perspective works by representing the light that passes from a scene through an imaginary rectangle (the picture plane), to the viewer's eye, as if a viewer were looking through a window and painting what is seen directly onto the windowpane.

  5. Mathematics and art - Wikipedia

    en.wikipedia.org/wiki/Mathematics_and_art

    Art has sometimes stimulated the development of mathematics, as when Brunelleschi's theory of perspective in architecture and painting started a cycle of research that led to the work of Brook Taylor and Johann Heinrich Lambert on the mathematical foundations of perspective drawing, [183] and ultimately to the mathematics of projective geometry ...

  6. Vanishing point - Wikipedia

    en.wikipedia.org/wiki/Vanishing_point

    A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections of mutually parallel lines in three-dimensional space appear to converge. When the set of parallel lines is perpendicular to a picture plane, the construction is known as one-point perspective, and their vanishing point ...

  7. Orthographic projection - Wikipedia

    en.wikipedia.org/wiki/Orthographic_projection

    Orthographic projection (also orthogonal projection and analemma) [a] is a means of representing three-dimensional objects in two dimensions.Orthographic projection is a form of parallel projection in which all the projection lines are orthogonal to the projection plane, [2] resulting in every plane of the scene appearing in affine transformation on the viewing surface.

  8. Technical drawing - Wikipedia

    en.wikipedia.org/wiki/Technical_drawing

    v. t. e. Drafter at work. Copying technical drawings in 1973. Technical drawing, drafting or drawing, is the act and discipline of composing drawings that visually communicate how something functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand ...

  9. Projective geometry - Wikipedia

    en.wikipedia.org/wiki/Projective_geometry

    Projective geometry formalizes one of the central principles of perspective art: that parallel lines meet at infinity, and therefore are drawn that way. In essence, a projective geometry may be thought of as an extension of Euclidean geometry in which the "direction" of each line is subsumed within the line as an extra "point", and in which a ...
