WebA polygon hidden surface and hidden line removal algorithm is presented that recursively subdivides the image into polygon shaped windows until the depth order within the window is found and thepolygon form of the output is the same as the polygon shape of the input. 386 PDF A Vector-like Architecture for Raster Graphics WebAbstract. The algorithm presented causes the elimination of hidden lines in the representation of a perspective view of concave and convex plane-faced objects on the picture plane. All the edges of the objects are considered sequentially, and all planes which hide every point of an edge are found. The computing time increases roughly as the ...

An algorithm which is often used is the one developed by Arthur Appel at IBM in the late 1960’s. “This ... WebA hidden-surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics [citation needed]. The process of hidden-surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider[citation needed]. chip cad
