Agents on a mesh
Little IronPython script to grow IVY on a mesh.

Current features:
Any number of spawn points
Number of [x] frames
Branching every [x] frames
Leaf spawn every [x] frames
Randomness [%]
Momentum [%]
Attraction to the sun (%)
Produce OBJ scatter matrix [Z to Y] or regular scatter matrix
Leaves are blocks to save RAM
Control leaf dimensions
CurvePiping mesh applied to branches automatically

Mismatched Techniques Combined

Note that the CA/Attractors was designed for internal organisation and thus is not hugely shown here, as this is an exterior/courtyard flythrough.

Rendertime about 6 hours per sequence (12) on a 3820 OC to 4.75GHz (with LQ AA and GI) 800x600.

Variably Extruded Recursive Subdivision

2012-10-29T02:44:37.959Z

GHPython
Each cell of the new generation has a 50% chance to subdivide. The extrusion amount is based on the cell generation (0-5 in this case) to create depth in a facade treatment.

Surfacing Pathways

2012-10-29T02:40:11.472Z

GHPython
Agent Based Point Attraction
Following Newton's laws of motion (universal gravitation)
"Comet" paths influence a gradiated grid which then gets surfaced with an ultra-low density marching cubes using the millipede component and a MeshToNurbs cluster found here on the forums.

All the values are relative, and the movement of the planets (due to the relative mass of the comets) is assumed negligible.

Cellular Automata Attractors and Repellers

Grasshopper + GHPython

Cellular Automata (Conway's Game of Life) generates attractors and repellers for these warped floor plates.
