I just do a tiny extension on inkscape.org
The extension is called:stroke-color-as-fill and do this.
But it bring posibilities to cool efects, so i do a large showcase
video. At the start I add a show case to add Delaunay triangulation in
2 steps to any inkscape art. Also you can use after my extension to fix
the rouding precission triangles.
I try now to fix the problem with custom markers to alow using it in a
saved document (middle of the video problem)
Take acount you can use a base biger than ~40px to allow more
resolution (more pieces,triangles...) -bus slowest- to the output
Bye , Jabier.
