most data sets have large polygons as well, the small average size is due to approximating curved surfaces with a set of triangles. 03/12/99 HP 4 - HP P Class 450/500/550/600/650/700/750 | hp visualize workstation - Graphics for - Page 6
skip the fx4+ and go all the way down to an fx2+, since the texture fill rate is likely the dominant characteristic. 03/12/99 HP 5 - HP P Class 450/500/550/600/650/700/750 | hp visualize workstation - Graphics for - Page 7

have been avoided in the past because the graphics subsystem wasn't fast enough, but might mean substantial productivity benefits with VISUALIZE-class graphics. Conclusion HP's VISUALIZE family of graphics accelerators for Windows NT deliver state-of-the-art features at a range of performance points
