A collaboration tool that allows multiple authors of a Grasshopper 3D design model to stream geometry to the web in real time is available at no cost by downloading a plug-in. The tool, called Platypus, works like a chat room for parametric geometry and allows on-the-fly 3D model mashups in a browser.
Since Platypus's late-April release, there have been hundreds of downloads from www.3dplatyp.us, reports the CORE studio|Thornton Tomasetti (TT), which developed and supports the tool.
