  2. Cohen–Sutherland algorithm - Wikipedia

    en.wikipedia.org/wiki/CohenSutherland_algorithm

    In computer graphics, the CohenSutherland 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). The algorithm was developed in 1967 during flight simulator ...

  3. Line clipping - Wikipedia

    en.wikipedia.org/wiki/Line_clipping

    The Nicholl–Lee–Nicholl algorithm is a fast line-clipping algorithm that reduces the chances of clipping a single line segment multiple times, as may happen in the CohenSutherland algorithm. The clipping window is divided into a number of different areas, depending on the position of the initial point of the line to be clipped.

  4. 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

  5. Sutherland–Hodgman algorithm - Wikipedia

    en.wikipedia.org/wiki/Sutherland–Hodgman_algorithm

    All steps for clipping concave polygon 'W' with a 5-sided convex polygon. The Weiler–Atherton algorithm overcomes this by returning a set of divided polygons, but is more complex and computationally more expensive, so Sutherland–Hodgman is used for many rendering applications. Sutherland–Hodgman can also be extended into 3D space by ...

  9. General Polygon Clipper - Wikipedia

    en.wikipedia.org/wiki/General_Polygon_Clipper

    The General Polygon Clipper (GPC) is a software library providing for computing the results of clipping operations on sets of polygons. It generalises the computer graphics clipping problem of intersecting polygons with polygons. The first release of GPC was designed and implemented in 1997 by Alan Murta.
