  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. 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

  4. 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.

  7. Sutherland–Hodgman algorithm - Wikipedia

    en.wikipedia.org/wiki/Sutherland–Hodgman_algorithm

    Note that if the subject polygon was concave at vertices outside the clipping polygon, the new polygon may have coincident (i.e., overlapping) edges – this is acceptable for rendering, but not for other applications such as computing shadows. All steps for clipping concave polygon 'W' with a 5-sided convex polygon

  8. 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.
