The Mach3 planner loads the buffer with movement data.
I suppose it could be viewed as a parametric polynomial. ;-) That type of motion interface is surprisingly common between PCs and intelligent motion devices, such as the Galil cards and I believe the Delta Tau cards, among others. I wrote a motion plug in for Mach3 a few years ago. Long ago Art, of Mach3, wrote up a long paper on how Mach3 functions internally and it is quite accurate.
