Today...I will hopefully be done with the retopo. :bit_uooh: It better be worth all the effort, so far I've reduced verts from 800k+ in the sculpt to around 60-70k so that alone is kinda cool #retopology #3d #blender #wip #beginner #vertices

@christianp The number of trees you need for a graph is called its arboricity — see https://en.wikipedia.org/wiki/Arboricity

It always equals the maximum, over subgraphs, of #edges(subgraph)/(#vertices(subgraph)-1), and can be computed in polynomial time.
