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
Clipping to the world-coordinates window is usually applied to the objects before they are passed through the window-to-viewport transformation. For a 2D object, the latter transformation is simply a combination of translation and scaling , the latter not necessarily uniform. [ 1 ]
The difference is that Liang–Barsky is a simplified Cyrus–Beck variation that was optimized for a rectangular clip window. The Cyrus–Beck algorithm is primarily intended for clipping a line in the parametric form against a convex polygon in 2 dimensions or against a convex polyhedron in 3 dimensions.
Typical elements of a window.The window decoration is either drawn by the window manager or by the client. The drawing of the content is the task of the client. In computing, a windowing system (or window system) is a software suite that manages separately different parts of display screens. [1]
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).
The clip coordinate system is a homogeneous coordinate system in the graphics pipeline that is used for clipping. [ 1 ] Objects' coordinates are transformed via a projection transformation into clip coordinates, at which point it may be efficiently determined on an object-by-object basis which portions of the objects will be visible to the user.
In computer graphics, the Liang–Barsky algorithm (named after You-Dong Liang and Brian A. Barsky) is a line clipping algorithm. The Liang–Barsky algorithm uses the parametric equation of a line and inequalities describing the range of the clipping window to determine the intersections between the line and the clip window.
Windowing may refer to: Windowing system, a graphical user interface (GUI) which implements windows as a primary metaphor; In signal processing, the application of a window function to a signal; In computer networking, a flow control mechanism to manage the amount of transmitted data sent without receiving an acknowledgement (e.g. TCP windowing)
