Data (vuo.data)
These nodes hold, share, and provide text descriptions of data within your composition. Some nodes work with a single value, while others work with a list of values.
The Hold Value
and Hold List
nodes can be used within a feedback loop to do something repeatedly or iteratively. For more information, see the Vuo Manual.
Example compositions:
- Record Camera Drags: Records interactions with a draggable camera and saves them to a file to be played back later. First, run this composition to display a 3D scene. While the composition is running, drag or scroll the mouse to change the camera perspective. The camera updates will be recorded and saved to a JSON-formatted file for as long as the composition is running. Then, to play back the recording in a high-quality offline render, use the File > Export > Movieā¦ menu option.
- Save Word Of The Day: Fetches a word's definition via RSS, and writes it to a text file on the Desktop.
- Show Bar Chart: Reads a CSV file and displays its contents as a bar chart.
- Store Mouse Position: Draws two dots that follow the mouse pointer. One dot stays with it constantly (purple), and the other only updates once per second (violet).
Nodes:
- Are Equal (Generic) (vuo.data.areEqual): Outputs true if all values are identical.
- Fetch Data (vuo.data.fetch): Loads or downloads a file from a URL.
- Hold Value (vuo.data.hold): When its refresh port receives an event, this node outputs its stored value.
- Hold List (vuo.data.hold.list): When its refresh port receives an event, this node outputs its stored list.
- Is Greater Than (vuo.data.isGreaterThan): Outputs true if A is greater than B.
- Is Less Than (vuo.data.isLessThan): Outputs true if A is less than B.
- Record and Play Values (vuo.data.record): Records a series of values to a file and plays them back.
- Save Data (vuo.data.save): Saves data to a file.
- Share Value (vuo.data.share): Outputs the input value.
- Share List (vuo.data.share.list): Outputs the input list.
- Summarize Value (vuo.data.summarize): Outputs a short text description of a value.
