Overview

The AxisAngle node calculates the angle, in degrees, between specific axes on two sites $i$ and $j$, which are referenced from Select nodes.

Description

AxisAngle is one of several calculation nodes that determine and store a numerical result, ready for retrieval and use by other nodes in a procedure.

AxisAngle determines the angle formed between specific axes on two oriented sites $i$ and $j$, mapping the origins of both axes to {0,0,0}. The resulting value is measured in degrees.

Options

Keyword	Arguments	Default	Description
`I`	Select	–	Site that represents $i$ in the angle $i$-$j$-$k$, taken from the named Select node.
`J`	Select	–	Site that represents $j$ in the angle $i$-$j$-$k$, taken from the named Select node.
`AxisI`	`X	Y	Z`
`AxisJ`	`X	Y	Z`

Control

Keyword	Arguments	Default	Description
`Symmetric`	`bool`	`false`	Whether to consider angles as symmetric about 90, mapping all angles to the range 0 - 90.
