Michel Beney,Marie-Geneviève Séréexpected-complexity analysis shows that, under a reasonable probability model, all three algorithms have linear expected running time. Experimental results indicate that two of these algorithms perform very well for some distributions, and are competitive with an existing method. Finally, we exhibit

The Edge Spread Function, which forms the basis for the antialiasing scheme, is given for the different filters. A decomposition approach reduces the problem of filtering an ar

The video image is partitioned by least significant bit on both axes, then regrouped into either rows or columns by a dedicated interconnection network. The selected access mode depends upon the currently executed graphics p

Implications of Research for Employers,thesis. The described algorithm is suitable for VLSI multi-processor implementation. Pipelined CORDIC processors are used as processing elements (PE’s). Basically, the algorithm implements the hemi-cube approximation technique, where the surface(patch)-to-hemi-cube projections are computed by ray-tr

Implications of Research for Employers,nd surface modeling tasks in CAD. Basic problems are nevertheless met when applying the .-splines to interpolation, where they have global behavior. We present a new class of cubic splines, the .2-splines, providing increased locality to the curve and surface interpolation tasks. Applications are al

Real scan-conversion is introduced as an extension of traditional integer based scan-conversion. It allows avoiding rounding operations. Real scan-conversion of circular arcs needs special care.

Beyond Computer Graphics and CAD/CAMnd early 1980’s. For the last few years the commercial field has been in a steady state mode, involving primarily incremental improvements. Current signs indicate that the field is poised to move again. However, the ultimate direction is unclear..This paper will review various NSF sponsored research
