Exercise 2 In this exercise, we want to clip the polygon in the image below with we are clipping the polygon above again, but this time with the Weiler-Atherton. Viewing and Clipping - Learn about Computer Graphics in simple and easy Circle Generation Algorithm, Polygon Filling Algorithm, viewing and Clipping, 2D Clip the polygon against each boundary of the clip region successively The Weiler-Atherton algorithm produces separate polygons for each visible fragment. 9. Aspect ratio. • Relative proportions of objects are maintained only if the aspect ratio of the viewport is the same as the aspect ratio of the clipping window. Mar 17, 2004 Set up vertex lists for subject and clip polygons. Ordering: as you move down each list, inside of polygon is always on the right side (clockwise).The Weiler–Atherton is a polygon-clipping algorithm. It is used in the areas like computer graphics, games development and others where May 6, 2015 Aug 13, 2018 Movavi Video Editor Review & Tutorial - Movavi Video Editor Step By Step Demo - Duration: 18:04. MOV Tutorials Recommended for you. The Weiler–Atherton is a polygon-clipping algorithm. It is used in areas like computer graphics and games development where clipping of polygons is needed. It allows clipping of a subject or candidate polygon by an arbitrarily shaped clipping polygon/area/region. It is generally applicable only in 2D.
