Kurt Squires holds a sieve containing all the material larger than 2mm across, from a core of sand and mud collected from Manukau Harbour. “This halo effect around the animal means that its influence is much greater than you might think.” “The animal is only a centimetre or two in size, but the pore water pressure gradient that it produces through its feeding can extend over 10-15 centimetres.” “The effect of the animal is much larger than its size,” says Conrad. As oxygenated water is drawn in from the surface, nutrient-rich water that fills the pores or spaces between the sand grains is, in turn, pushed back up to the surface where it becomes available to the microscopic plants.Ĭonrad says that the wedge shell plays a key role in the way nutrients are recycled between the oxygen-rich surface layers of the estuary, and the deeper black oxygen-poor or anoxic muds below. This is important, says Conrad, as it creates a pressure differential. “The thing about this animal,” says marine biologist Conrad Pilditch, from the University of Waikato, “is that for all kinds of funky reasons, the exhalant siphon is at depth – probably to avoid it being eaten … so it’s bringing water in at the surface and pumping it out at depth.” The plants are filtered out as the water is sucked across the animal’s gills, and the ‘used’ water is then pumped back out another, much shorter, siphon. The bird-like tracks are made as the animal extends its long feeding siphon to the surface and sucks up shallow water containing microscopic plants – the microphytobenthos – that bloom there each low tide. I would be very interested in Unreal 4 becoming the new tool for me to use.What look like numerous small bird footprints on the silty surface of the sand flats are in fact feeding traces. I personally have my background in using a programming language called Quartz Composer which is losing support from its developers and becoming more outdated. The real time rendering capabilites, among everything else, could provide a wonderful new tool for a lot of us. I searched the forums and didn’t get any results so I figure I would post a request.

One said he would look at the Unreal plugin API but I wanted to see if anyone suggested it. Well after seeing the Unreal 4 demo a lot of us were joking around wouldn’t it be nice to get some native support for OSC ( ), MIDI, and Syphon ( ) for Unreal. WORKSHOP 3D INTERACTIVE PROJECTION MAPPING - UNITY 3D on Vimeo NuFormer, 3D Mocap Mapping - NuFormer/Motek, the Netherlands - March 2012 - Short Version (20 min) - YouTube In example Unity engine has allowed interactive projection mapping such as these examples: In recent years game engines that offered real time rendering have provided an interesting tool for us to work with. We often work in many different programming environments with various tools to try to accomplish our visions whether simple generative graphics or projection mapping. I came here on behalf of some of my fellow live visual artist developer friends, casually called VJs.
