It is possible to do it on the parabolic blends as well. That was actually the original plan. The downside of doing it that way is that the it's hard to isolate tangential acceleration from the total acceleration, since they aren't always perpendicular. It also makes the trapezoidal velocity profile a bit more complex. I'm hoping that tangent arcs solve enough of the slowdown that we won't need to optimize the remaining parabolic blends.

Is the back-propogation of the maximum speed (which I think was your "rising tide" optimisation) only possible with the circular arc blends, or can it also be applied to the current parabolic blends? Of course, if you would rather do the work than explain the work, that's fine. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
