Thanks for confirming that, Sam. Julian, I think the reason for the slowdown is there are a lot of arc-arc intersections, which fall back to parabolic blends. It will run slower (slightly) than the original because of a crude fix I made to arc acceleration. I cut the circular arc acceleration in half for parabolic blends to prevent a violation in this code:
http://pastebin.com/Dpyr1jrY The problem with this fix is that it's a relatively rare case, and the cost is noticeable (as you can see with your code). In the long term, the fix for this is to add line-arc and arc-arc blends. I've prioritized other features since it's a lot of work for a relatively small gain, but I'm hoping to add these features in the future. -Rob On Mon, Dec 30, 2013 at 7:37 AM, sam sokolik <sa...@empirescreen.com> wrote: > I just ran your program in my config.
