From: Han on 11 Mar 2010 21:00 Can anyone explain briefly what happens when one graphs via FAST3D? Does the HP50G go into ARM mode to do the fast number crunching during the computing stage? Or is it still using Saturn code? I am familiar with how FAST3D rotates so quickly (using the DRAW3DMATRIX engine), but I would like to know how the compute the array of z-values so quickly. Thanks ahead of time, Han

So the "Computing" part of FAST3D graphs is done in Saturn code and not Arm code? That's pretty impressive for number crunching... |
