What vvvv is
vvvv is a visual live-programming environment for .NET, intended to cover rapid prototyping through production. Changes in visual patches or C# are applied live while compilation runs in the background. The software is presented for interactive spaces, custom media servers, realtime graphics, and interactive media applications. It can coordinate applications across multiple PCs and synchronize rendering for large LED screens with NVIDIA Quadro Sync cards. Listed integrations include VIOSO and Scalable Display Systems projector calibration, Augmenta and BlueIOT crowd tracking, OptiTrack and Captury motion capture, and VST3 audio plugins. Its VL visual language uses .NET libraries; projects can also use C# or F#, with Python embedding through CSnakes. Exports include Windows desktop and console apps plus Linux and macOS console apps, with on-premise deployment described. Evaluation, non-commercial, FOSS, contribution, teaching, and learning use is free. Commercial projects require a per-developer license. The maker says there is no copy protection, feature limitation, or mandatory registration.
