Here a different use of Gradient Flow.
I have a Voronoi pattern that needed to be printed with just one path
Of the idea is to offset it, make a Spanning tree that links the cells
And then bridge the cells
Lets say I put a weight of 100 of the red dot and 0 at all others places. And then I smooth the weights. I could also use geodesic distance or heat flow.
Gradient Flow of the weight gives that
Weight Smoothing Cotan Weight Method
Weight Smoothing Edge Length Method/Uniform method
