Differential Growth describes a surface that grows at different rates in different locations. Biological systems can create complex forms from the interaction of physical properties of a surface and simple controls of growth rates over time. Source - Nervous System
Circle Packing
Differential Curve Growth
2D - Splitting or Differential Curve Growth is an algorithm to divide a polyline into smaller segments to fill up a constraining volume or surface while preventing self-intersection through the use of circle packing.
Closed Mesh Differential Growth
Open Mesh Differential Growth
Mesh differential growth works on the concept of pushing vertices away from each other by calculating collisions with neighboring vertices within a threshold distance range. The mesh is split at faces where the edge is exceeding the threshold which resembles growth of mesh edges. Open and close meshes both exhibit a different pattern of growth open mesh resembles forms like pedals whereas close meshes resemble cellular venation.
