Such as the selector switches between the pixel data and the lookup tables, and between the lookup table outputs and the DAC inputs. In pseudo-C pseudo-code, the per-pixel operation was not DACinput[chan] = cmap[chan][pixeldata[chan]] but rather DACinput[chan] = cmap[sw2[chan]][pixdata[sw1[sw2[chan]]]] where sw1[] and sw2[] are three-element arrays each element of which can hold only one of three values. Of course, it's questionable how necessary this is when you can rerender a multi-mega-polygon scene afresh during the vertical retrace interval, but that's a different issue...especially when you the buyer of the video card essentially can't get the information necessary to write the software to drive that rerendering. ...in some respects. Most of their fancies, though, are aimed at high frame rate when doing 3D rendering, and don't even notice other possibilities. /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse at rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
