WebAccelerating Polygon Clipping Bengt-Olaf Schneider 1 ABSTRACT Polygon clipping is a central part of image generation and image visualization sys tems. In spite of its … Webthe geometry parts of the polygon clipping results will be collected during the union operation, it’s difficult to parallelize it for the uncertainty of intersecting between polygons of different layers. The polygon intersection-spreading problem is the main factor predisposing the uncertainty and resulting in the many-to-many ...

WebTraditionally, polygon clipping has been used to clip out the portions of a polygon that lie outside the window of the output device to prevent undesirable effects. In the recent past polygon clipping is used to render 3D images through hidden surface removal and to produce high-quality surface details using techniques such as Beam tracing. WebThe Vatti clipping algorithm [1] is used in computer graphics. It allows clipping of any number of arbitrarily shaped subject polygons by any number of arbitrarily shaped clip …
