Updated Voronoi_inkscape_1.4.2.zip<\/a> extension to work with Inkscape 1.4.2! (ver 1.1<\/a>, ver 1.3<\/a> of the extension.). To install, go to Inscape -> Extensions -> Manage extension -> Install packages tab -> click on file icon and select the zip file.<\/p>\n\n\n\n

Takes as input a shape to fill with a Voronoi diagram. The number of levels of recursive Voronoi diagrams can be set.<\/p>\n\n\n\n

Options<\/strong><\/p>\n\n\n\n

Random seed points: Number of starting points. The distribution of the starting points is set for each level of the diagram.<\/p>\n\n\n\n

Options:<\/strong>
Levels of recursion: Within each Voronoi region, a new Voronoi diagram is created.<\/p>\n\n\n\n

Level(rand_type):relax,\u2026: Sets of parameters for each Voronoi diagram level.
<level>(<normalization method>[param1=n;parms2 = n.n; params3=foo\u2026]):<Llyod\u2019s relaxation interations>
The randomization type can be \u2018normdist\u2019, \u2018normdist_edge\u2019, \u2018random\u2019. \u2018Random\u2019 distributes the seed points randomly. \u2018Normdist\u2019 distributes the seed points around one or more \u2018centers\u2019 (default is 1 center), distributed around the centroid. \u2018Normdist_edge\u2019 moves the seeds away from the centers toward the edge.
Llyod\u2019s relaxation moves each of the points halfway between its current position and the centroid of the Voronoi polygon it is located in with each iteration.<\/p>\n\n\n\n

Parameters:<\/strong>
centers = 2 \u2013 Number of centers to cluster \u2018normdist\u2019 random points around. Centers are spaced at center_dist from the centroid of the input path.
keep_centers = 0,1,3\u2026 \u2013 Which of the centers to use. Numbering starts at 0.
center_dist = 1.23 \u2013 Distance from the path centroid to place the random seed centers. dist = size \/ center_dist. Default = 2.0. Large numbers push the centers towards the edge.
min_dist = 1.23 \u2013 Minimum distance of random points from the edge of the path. In Inkscape units. Default = 5.
sd = 1.23 \u2013 Standard deviation of the random points. sd = standard deviation of the random points. sd = size \/ sd. Larger numbers give a tighter distribution. Default = 2.5.
xy = x1,y1, x2,y2\u2026 \u2013 Explicitly enter random seed point locations. In Inkscape units. Overrides random dist center parameters.<\/p>\n\n\n\n

Return lines or polygons<\/strong>: The Voronoi regions are added to the document as polygons or lines.<\/p>\n\n\n\n

Examples:<\/p>\n\n\n\n

340 mm diameter circle as a polygon of 30 points.
Parameters: 1(normdist[centers=3;center_dist=1.2;sd=4.14;min_dist=25]):1<\/p>\n\n\n\n

\"\"<\/p>\n\n\n\n

Two levels of recursion:<\/p>\n\n\n\n

Parameters: 2(normdist[centers=3;center_dist=1.2;sd=4.14;min_dist=25]):1, 1(normdist):1<\/p>\n\n\n\n
