trying out diffusion limited aggregation on a mesh. when a sphere intersects a node of the mesh that node 'grows' outward along its normal vector by a set distance. When the edges in the mesh get too long the subdivide, and when they get to short they collapse.
The center portion of the video was sped up.
need to try: changing spawning plane for spheres to speed up growth but allow for taller structures
-maybe distribute 'nutrients' between vertices. When a vertices grows, all its neighbors do to, but by an amount proportional to their distance. or something.
inspired by (or rather a cheap knock off from): Spontaneous Branching in a Polyp Oriented Model of Stony Coral Growth and related papers
