Interactive

Method #

Interactive nodes process transforms based on various kinds of live inputs. Most work with transforms, although the RSS Feed Node and RSS Text Selector output a text string, and the clock time modifier outputs float values.

Array nodes are a particularly notable subgroup. These nodes process multiple transforms at once, and can be used to generate multiple copies of a node at those transforms. Sources are usually external, e.g a CSV file or TUIO data, but Arrays can be generated from internal data too with the Transform Array node.

Array Operators

These nodes take transform arrays as input and applies operations to them.

Array Average	Combines the points from an array to a single transform.
Array Copy	Creates a copy of the points from an Array.
Array Element Extractor	Extracts an individual point from an Array.

Array Sources

These nodes act as sources for Array data.

Blacktrax Array	Generate an array using multiple Blacktrax Trackables as a source.
CSV/Table Array	Generate an Array using a CSV file as a source.
Exposable Array	Generates an Array passed through from a media server.
Hokuyo UST Lidar Array	Generates an Array from a Hokuyo 2D LiDAR.
Mouse Point Array	Generate an Array using the mouse cursor as a source.
Transform Array	Generate an Array using internal Notch sources.
TUIO Array	Generate an Array from TUIO data.
Windows Touch Array	Generate an Array from Windows touch data.

Nodes

Artnet Recording Playback	Playback recorded ArtNet data from Notch Builder's built-in ArtNet recorder.
Blacktrax Tracked Body	Generates a tracked point from Blacktrax.
Hot Zone	This node detects if the centre point of an object moves into a region.
RSS Feed Node	The RSS Feed node combs data from an RSS feed from the Internet.
RSS Text Selector	Extracts a text field from an RSS feed.
VR Controller	Contains the transform data from a connected VR controller.
VR Look-At Trigger	trigger effects based on where a VR camera is looking.
