Grasshopper <-> Processing talk via UDP luis2009-07-20codeNewsResearchScripting1 Comment The following videos show communication between Grasshopper and Processing via the UDP protocol. This is an example of communication through UDP in vb.net and processing. There is one receiving processing sketch which is listening to UDP data from another processing sketch and a grasshopper definition. This is an example of getting data (although very simple) into Grasshopper via UDP. The issue arrises from the udpClient.receive method which blocks the application until it receives data. This means Grasshopper is frozen until it receives data. Currently working on different strategies to fix this either asynchronously or via a different protocol.
