<div dir="ltr">Unfortunately the algorithms only work in 2D, and probably aren't actually efficient. I have been meaning to generalize some of them now that Pict3D exists :) And they would probably serve as reference implementations. </div> <div class="gmail_quote">On Tue, Mar 17, 2015 at 1:56 PM Neil Toronto <<a href="mailto:neil.toronto@gmail.com">neil.toronto@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">That looks like an awesome project. I could probably even use the convex hull implementations in Pict3D. You could use `plot-bitmap` or `plot/dc` as well, FWIW. I'll count this as a +1, then. :) Neil ⊥ On 03/17/2015 01:51 PM, Spencer Florence wrote: > I've been using plot heavily for > <a href="https://github.com/florence/convex-hulls" target="_blank">https://github.com/florence/convex-hulls</a>, which pulls a bitmap% from the > snip% to render it as a gif.
