Line and area clipping algorithm
Nettet1. mai 2012 · This paper proposes a new line clipping algorithm for 2D space which is more efficient than the existing algorithms. The possible extended algorithm for 3D … NettetTherefore, this paper presents a novel algorithm for clipping real-scene 3D models with LODs based on boundary lines that fit the surfaces of the models. The algorithm can clip a model flexibly from different viewing angles, can use a curve that fits a model surface to finely clip the model, and can clip each level of an LOD-based 3D model ...
Line and area clipping algorithm
Did you know?
There are two common algorithms for line clipping: Cohen–Sutherland and Liang–Barsky. A line-clipping method consists of various parts. Tests are conducted on a given line segment to find out whether it lies outside the view area or volume. Se mer In computer graphics, line clipping is the process of removing (clipping) 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. Se mer In computer graphics, the Cohen–Sutherland algorithm (named after Danny Cohen and Ivan Sutherland) is a line-clipping algorithm. The algorithm divides a 2D space into 9 regions, of which only the middle part (viewport) is visible. In 1967, flight … Se mer 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 Cohen–Sutherland … Se mer This algorithm classifies vertices against the given line in the implicit form p: ax + by + c = 0. As the polygon is assumed to be convex and vertices are ordered clockwise or anti-clockwise, … Se mer The Liang–Barsky algorithm uses the parametric equation of a line and inequalities describing the range of the clipping box to … Se mer Very similar to Liang–Barsky line-clipping algorithm. The difference is that Liang–Barsky is a simplified Cyrus–Beck variation that was optimized for a rectangular clip window. Se mer This algorithm has similarities with Cohen–Sutherland. The start and end positions are classified by which portion of the 9-area grid they occupy. A large switch statement jumps to a specialized handler for that case. In contrast, Cohen–Sutherland … Se mer NettetClipping Lines If both endpoints of a line lie inside the viewport, no clipping is necessary, as the line segment is completely visible. If only one endpoint is within the viewport, then we must clip the line at the intersection. If both endpoints are outside the viewport, then the line crosses two boundaries, or is completely outside the viewport.

However these tend to be complicated algorithms when all of the edge cases are taken into account. One implementation of polygon clipping that you can use your favorite search engine to look for is Weiler-Atherton. wikipedia article on … Nettet1. mai 2012 · This paper proposes a new line clipping algorithm for 3D space against a cuboid which is not generated based on Cohen-Sutherland or Liang-Barsky line clipping algorithms.

Nettet30. jan. 2024 · Weiler-Atherton polygon clipping algorithm. This algorithm helps us to clip a filled area. The filled area may be a convex polygon or concave polygon. This … Using the Nicholl–Lee–Nicholl algorithm, the area around 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. This initial point should be in three predetermined areas; thus the line may have to be translated and/or rotated to bring it into the desired region. The line segment may then be re-translated and/or re-rotated to bring it to the original position. After that, straight line segments are drawn fr…
