WebNow we want to clip a polygon against our view-frustum. To do so, we first need a clipping routine to clip a line against a plane. Afterwards we'll extend this to polygons vs. planes and finally to planes vs. frustum. Clip a 3D-line against a plane. A line in 3D-space is defined by two points (let's call them A and B). WebDec 4, 2024 · The Liang-Barsky algorithm is a line clipping algorithm. This algorithm is more efficient than Cohen–Sutherland line clipping algorithm and can be extended to 3 …

WebPoint Clipping: Point Clipping is used to determining, whether the point is inside the window or not. For this following conditions are checked. x ≤ x max x ≥ x min y ≤ y max y ≥ y min The (x, y) is coordinate of the point. WebThis Algorithm was developed by Liang and Barsky. It is used for line clipping as it is more efficient than Cyrus Beck algorithm and Cohen Sutherland algorithm because it uses more efficient parametric equations to clip the given line. These parametric equations are given as: x = x1 + tdx. y = y1 + tdy, 0 <= t <= 1.

WebNov 13, 2024 · Real-Time Uses: In computer graphics, the Nicholl–Lee–Nicholl (N-L-N) algorithm is a clipping algorithm used to remove parts of lines that lie outside a user-specified window. The N-L-N algorithm is one of many algorithms that can be used to clip lines. It is a simple algorithm that can be implemented easily and efficiently. WebThe Sutherland–Hodgman algorithm is an algorithm used for clipping polygons. It works by extending each line of the convex clip polygon in turn and selecting only vertices from the subject polygon that are on the visible side.
