Arrow

A shafted arrow surface starting at a chosen point and pointing in a chosen direction, which can be wired in as a 3-element array.

Inputs

None.

Added from the Parameters pane (⊕). While connected, each drives its parameter.

Port	Accepts	Mode	Description
`start` Start	primitive(array) dataset(stack) dataset(surface)	opt-in	start position; overrides the start parameter while connected
`direction` Direction	primitive(array)	opt-in	Direction as a 3-element array, read in the current direction frame; overrides the Direction row while connected
`tip_length`	primitive(number)	opt-in drives `tip_length`	Drives the Tip Length parameter while connected
`tip_radius`	primitive(number)	opt-in drives `tip_radius`	Drives the Tip Radius parameter while connected
`shaft_radius`	primitive(number)	opt-in drives `shaft_radius`	Drives the Shaft Radius parameter while connected
`scale`	primitive(number)	opt-in drives `scale`	Drives the Scale parameter while connected
