Nodes are the building blocks of Vuo, which you can assemble in any way you can think of to create compositions. When you download Vuo, it comes with a large set of nodes that support 2D and 3D graphics, video, audio, networking, user interaction, and more. If you’ve purchased Vuo Pro, then you have some bonus nodes available to you. Whether you’re using Vuo Community Edition or Vuo Pro, you can also download nodes by third-party developers to add to your collection.
