STRANGLER VINE

ANALOGUE OF STRANGLER VINE

Growing in tropical and sub-tropical regions of Australia. The above photographs show a variety of Strangler Fig vines species.

Project One explored analogues of the Strangler Vine through iterative physical models. Draping waxed rope over various surface contours gave insight and clues for developed and abstraction in a digital modelling space.

Exploration from Project One


v01

SLIDE* BOID definition This definition’s expression is very close to my PROJECT 1 ANALOGUE. The logic moves points over a curved surface, that is, agents respond to a surface condition. My waxed rope behaves in the same way, where rope is placed on a waveform curved surface - responding to the surface condition. The SLIDE* definition is a useful tool for generating points over a surface and holds a lot of potential - further exploration is required of both clusters and individual organic plant roots/ stems generated by this definition. This script shows potential for creating long climbing or crawling vine stems. Further testing with explore its capacity for randomly generating ‘bait’ with-in an elongated, potentially cylindrical, domain to attract agent flock; mimicking vine growth around/ along a tree truck or host plant.

The rocky southern point is an exposed coastal terrain that expresses a variety of geographical features. The rugged nature of this coastline is predominently volcanic rock, sand and ocean spray. There are a select few rock formations that stand out as dramatically features on site enhanced by the restless waves and tides. These defining elements make the site both a challenging and dynamic area; with 3 clearly defined topographic conditions: pebble and black-sand beach, jagged rock formations and native vegetation - small shrub, flax, succulent and mosses. Further exploration and targeted analysis of particular points will be necessary for successfully establishing dialog between geological points and botanical bio-type - Strangler Vine.

Mesh from curves with mesh from INVERTED curves creates a terraform that is easier to understand. GREY surface represents flat ground contitions. KHAKI surface represents rock and vegetated areas. This approximation of surface contions provides a detailed MICRO surface for the Vine BIOTYPE to grown in respond to. This method of site analysis provides greater information for the selecting areas for the VINE to spawn from.

POA 03: Site Photograph The natural arch within POA 03 rock formation was an exciting discovery. WWC Council 1M Countour Lines have recorded the formation as approximately 5-6 m in height - this seems roughly correct and also confirms the IMAGE SAMPLED terraform is appropriately scaled.

Cross sections through the open-meshes of the Crawler Vine Body hold intriuging potential as a soft architecture. Further developement of its utilisation on-site might afford refuge from strong southerly wind and sea swell conditions. The Crawling Vine Bodies might provide tunnels with openings for people to walk through. The openings migh provide surfers with a safer way to navigate over rocks. The nature of this BIO-TYPE lends itself to larger and smaller scales. RIGHT: Red lines indicate potential pathways for the vine to grow that provides enough stability and utility for visitors to the site.
