1. Analysis of visual structure in Japanese dry rock gardens : Improved HST medial axis software (Van Tonder & Ejima, 2003) was created for a Sun Blade workstation and MATLAB GUI developed for use on windows machines. HST analysis of rock gardens shows a clear division between Muromachi shoin-style karesansui and strolling/tea gardens from the same or later periods. In the latter, the global structure is too diverse to allow meaningful comparison. Older gardens from the Rinzai school of Buddhism were found to pertain in most cases to the convergent configuration of medial axis lines. Besides Ryoanji (Myoshinji), the following gardens are striking examples : Nanzenji hojo, Daitokuji hojo, Shinjuan (Daitokuji), Ryugenin (Daitokuji), Entsuji (Myoshinji), Zakkein (Myoshinji). Formal structural analysis involved fractal analysis, and graphing of higher order properties, like average path length, branch angle and branch angle symmetry (Van Tonder, in press). Results show that the above garde

ns closely mimic natural tree-like patterns. Of all the gardens considered, Ryoanji most purely resembles structural characteristics of biological trees, whereas Zakkein had the greatest complexity. Alterations to Zakkein in the late Edo period or thereafter, seriously diminished its degree of naturalness. Some Edo period gardens superficially follow the tree-shaped layout, but analysis shows that it merely imitates the old style without grasping how to achieve the same degree of naturalness. Unfortunately Zakkein was recently destroyed - a great cultural loss for Japan. I conclude that the visual structure in shoingardens of Rinzai temples - Myoshinji, Nanzenji and Daitokuji - is unique, reflecting the sophistication acquired at some point in the history of Japanese landscape architecture. Based on the high degree of accuracy by which visual structure is represented in historical garden illustrations, I conclude that convergent spatial structure in landscape design has perceptual advantages, namely that it suits internal representation of space in the human visual system.
