  2. Viewport - Wikipedia

    en.wikipedia.org/wiki/Viewport

    In 3D computer graphics, the viewport refers to the 2D rectangle used to project the 3D scene to the position of a virtual camera. A viewport is a region of the screen used to display a portion of the total image to be shown. [4] In virtual desktops, the viewport is the visible portion of a 2D area which is larger than the visualization device.

  3. Cohen–Sutherland algorithm - Wikipedia

    en.wikipedia.org/wiki/Cohen–Sutherland_algorithm

    In computer graphics, the Cohen–Sutherland algorithm is an algorithm used for line clipping.The algorithm divides a two-dimensional space into 9 regions and then efficiently determines the lines and portions of lines that are visible in the central region of interest (the viewport).

  4. Warnock algorithm - Wikipedia

    en.wikipedia.org/wiki/Warnock_algorithm

    Polygon visibility in a given viewport: a) polygon fills the viewport, b) polygon partially and c) completely visible, d) polygon invisible. Four steps of a viewport divisions for a simple scene. The Warnock algorithm is a hidden surface algorithm invented by John Warnock that is typically used in the field of computer graphics. [1]

  5. Image plane - Wikipedia

    en.wikipedia.org/wiki/Image_plane

    In 3D computer graphics, the image plane is that plane in the world which is identified with the plane of the display monitor used to view the image that is being rendered. It is also referred to as screen space .

  6. Viewing frustum - Wikipedia

    en.wikipedia.org/wiki/Viewing_frustum

    A view frustum The appearance of an object in a pyramid of vision When creating a parallel projection, the viewing frustum is shaped like a box as opposed to a pyramid.. In 3D computer graphics, a viewing frustum [1] or view frustum [2] is the region of space in the modeled world that may appear on the screen; it is the field of view of a perspective virtual camera system.

  7. Graphics pipeline - Wikipedia

    en.wikipedia.org/wiki/Graphics_pipeline

    The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]

  8. Clipping (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Clipping_(computer_graphics)

    Clipping, in the context of computer graphics, is a method to selectively enable or disable rendering operations within a defined region of interest. Mathematically, clipping can be described using the terminology of constructive geometry. A rendering algorithm only draws pixels in the intersection between the clip region and the scene model.

  9. Line clipping - Wikipedia

    en.wikipedia.org/wiki/Line_clipping

    In computer graphics, line clipping is the process of removing lines or portions of lines outside an area of interest (a viewport or view volume). Typically, any part of a line which is outside of the viewing area is removed. There are two common algorithms for line clipping: Cohen–Sutherland and Liang–Barsky.
