Volume rendering delivers the inside perspective

摘要

Mitsubishi is poised to enter production with its first hardware volume-rendering chip, the vg500, which the company implements on the PCI 2.1 -compatible, $2500 (10) VolumePro board. Although tile-based rendering implements a unique approach to handling the polygon-to-pixel translation in 3-D graphics accelerators, both it and conventional rendering use the same graph-ics-input-primitive set: an interlocking series of varying-sized, pattern-texured polygons applied to a wire-frame skeleton (see "Getting glitzy with graphics for embedded systems," pg 79).
