Released on 2014.04.24

This release adds many new nodes and other features, including:

  • Nodes for audio input/output, useful for music visualizations, sound effects, and audio playback
  • Nodes for keyboard input, useful for adding keyboard controls or text input to graphics windows
  • Nodes for iterative graphics, useful for drawing multiple 2D or 3D objects at a time
  • Improved support for UI design
    • Nodes for animation
    • Nodes for interaction with layers
    • Nodes for layers with shadows
  • Improved support for using Vuo compositions as plugins in 3rd-party applications
    • Ability to create a composition whose published ports match a protocol (Image Filter or Image Generator), providing an interface between the composition and the application
    • Reduced Vuo framework size by 25%
  • Added an "event throttling" setting to help prevent compositions from slowing down when events are firing faster than the user's computer can process them

  • Fixed the composition not being marked as modified if you save and then undo. [#3332]
  • Fixed the composition being marked as modified if you save, then make a change, then undo. [#3332]
