Properties

Property	Description
Settings
Origin	Defines how the base direction is computed, either from the Node to the neighbor (going outward), or from the Neighbor to the node (going inward).
Direction Source	Select where to read the direction to compare to from; either `Constant` or `Attribute`.
Direction Constant	Fixed test direction.
Direction Attribute	Per-point direction attribute.
Transform Direction	If enabled, will transform the input direction (either `Constant` or `Attribute`) using the point’ transform.

Property	Description
Comparison	Which comparison to use. See Numeric comparisons.
Dot Units	Let you choose to work either with normalized dot range (`-1 / 1`) or degrees. This affects how the attribute Dot value will be interpreted as well.
Unsigned Dot	When enabled, the comparison will occur against an absolute dot value. This is especially useful when testing against undirected lines.
Dot Value	The type of value used for this probe’ search radius; either a `Constant` value or fetched from an`Attribute`
(Dot or Degrees) Constant	Constant to compare against.
(Dot or Degrees) Attribute	Constant to compare against.
(Dot or Degrees) Tolerance	Comparison tolerance, if the selected comparison is an approximative (`~`) one.

Output	Description
Direction Attribute `FVector`	If enabled, writes the `Edge`’ direction to the specified attribute.
Invert Direction	If enabled, will invert (`-1`) the direction output above.*
Length Attribute `Double`	If enabled, writes the `Edge`’ length to the specified attribute.
Edge Index Attribute `Int32`	If enabled, writes the `Edge`’ point index to the specified attribute. This is useful for targeted/cherry-picking manipulations.
Vtx Index Attribute `Int32`	If enabled, writes the `Vtx`’ point index the selected `Edge` connects to, to the specified attribute. This is useful for targeted/cherry-picking manipulations.
Neighbor Count Attribute `Int32`	If enabled, writes the `Vtx`’ point neighbor count the selected `Edge` connects to, to the specified attribute. Amongst other things, this can come in handy to drive the 🝰 Heuristic Attribute.
