An Efficient Algorithm For Hidden Surface Removal Ketan Mulmuley The University of Chicago 1 Abstract We give an efficient, randomized hidden surface removal al- gorithm, with the best time complexity so far. A distinguish- ing feature of this algorithm is that the expected time spent. Hidden Surface Removal - Viewing - Looking along any projector (from center of projection, for example) we see one or more surfaces. Hidden Line - when outline of an object is to be displayed - similar to clipping a line segment against a window - most surface algorithms can be applied for hidden line elimination. Hidden Line Removal. A 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. The process of hidden surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. The analogue for line rendering is hidden line removal.
