The fast identification of shadow regions due to area light sources is necessary for realistic rendering and for discontinuity meshing for global illumination. A new shadow-determ...
We describe an algorithm for estimating the number of page fetches for a partial or complete scan of a B-tree index. The algorithm obtains estimates for the number of page fetches ...
This paper attempts to de ne an object-oriented database system. It describes the main features and characteristics that a system must have to qualify as an objectoriented databas...
