    Intersection calculations dominate the run time of canonical ray tracers. A common algorithm to reduce the number of intersection tests required is the intersection of rays with a tree of extents, rather than the whole database of objects. A shortcoming of this method is that these trees are difficult to generate. Additionally, manually generated trees can be poor, greatly reducing the run-time im... View full abstract»

    It is sometimes necessary to orthogonally reorient bitmap images. Traditional techniques for doing so are difficult to implement on classically organized bitmap memory systems because of their raster-scan ordering of images. In some cases, this can require several hundred times more processor activity, and many times more memory references, than are required to bitblt an image. This article descri... View full abstract»

    In implmenting rater grahic algorithms, it is impotant to toroughly understand behavior and implicit defaults inherent in each algorithm. Design choices must balance performance with respect to drawing speed, circult count, code space, picture fidelity, system complexity, and system consistency. For example, "close" may sound appealing when describing the match of the rastered representation to a ... View full abstract»

    Geometric set operations play an integral role in systems for CAD/CAM, for robot planning, and for modeling objects such as underground formations from empirical data. Two major issues in the implementation of geometric set operations are efficiency in the search for geometric intersections and effectiveness in the treatment of singular intersection cases. This article presents an algorithm for ge... View full abstract»
