Web23 de abr. de 2012 · Now computing the parts of an edge which are hidden by a contour polygon is the main course. This problem is very close to that of clipping a line segment by a polygonal window in 2D. First consider the line of support of the line segment and find intersections with the polygon. WebIn hidden-line removal, edges or other vectors in the model that are obscured by visible surfaces are omitted from the display of the image, or displayed as dashed rather than full lines. An alternative name for the technique is visible line identification. Some of the common hidden line algorithms are . Floating horizon ; Image space; List ...
