DEEP RESEARCH ON BRANCHING SYSTEM

http://www.opensysdesign.com/2007/09/b.html
This is a website I found can be useful to help people understand branching system. Branching system is an open system in which a system continuously interacts with its environment. It may be defined an entity with inputs that changes its behavior in response to conditions outside its boundaries. It may be defined as the region of space characterized by a collection of components or elements related in some way.

A Geometric Comparison of Branching Structures in Tension and in Compression versus Minimal Paths ,Von Buelow, Peter,International Association for Shell and Spatial Structures.
This is a book I found on teh internet, and it illustrates braching system in various ways. Branching structures are based on geometric systems that expand through bifurcation without returning to form closed cells. In this sense, branching structures resemble the structure of trees that branch continually outward. In architectural engineering, these forms can be used either as tension or compression systems. Form finding techniques based on models have been used in the past to study these forms. Although thread models can be effective in the study of force paths, they cannot distinguish between tension and compression and have no way to take member buckling into account. But buckling does have an influence on appropriate geometry of a compression system. Also, minimal paths have been used to explore possible geometries for branching structures. Both surface tension thread models dipped in water, and weighted string models are shown in comparison with ideal tension and compression forms found with a computational method based on Genetic Algorithms.

5 EXTRA IMAGES OF BRANCHING

 This is an system image of human's lung. As can be seen from here, even organs can gave a sense of aesthetic and in special geometry system. The direction of blood capillary is totally opposite from tree braching. But this irregular branching method increase the aesthetic perception of lung system.

This is a leave of a palm tree. Compared to lung capillary, this konf of structrue is more regular and neat. Every branch is in the same position and same lengths and thickness.

Flower is another type of branching structure. Every petal come out from a same trunk and in each level, the size as well as the thichness of the petals are different.

 Coral prefers to be a natural branching structure which grow slowly and elegent.

 This is somebody's OS branching structure which is an exeggeration of leave brancing.

TUTORIALS FROM DISCUSSION FORUM

This tutorial is to teaching people use voronoi to create a hollow plan with relative thickness and its helpful to me.

This is a tutorial on generative algorithms focusing on creating weaving style models (like textiles and fabrics) in grasshopper.
