# Rotate Euler Reference Frame

## Group (Subgroup)

Orientation Analysis (Conversion)

## Description

This **Filter** performs a passive rotation (Right hand rule) of the Euler Angles about a user defined axis. The *reference frame* is being rotated and thus the *Euler Angles* necessary to represent the same orientation must change to account for the new *reference frame*.  The user can set an *angle* and an *axis* to define the rotation of the *reference frame*.


### Input Parameter(s)

| Parameter Name | Parameter Type | Parameter Notes | Description |
|----------------|----------------|-----------------|-------------|
| Rotation Axis-Angle [<ijk>w] | Vector of Float32 Values | Order=i,j,k,w (Deg) | Axis-Angle in sample reference frame to rotate about. |

### Input Data

| Parameter Name | Parameter Type | Parameter Notes | Description |
|----------------|----------------|-----------------|-------------|
| Input Euler Angles | Array Selection | Allowed Types: float32 Comp. Shape: 3 | Three angles defining the orientation of the Cell in Bunge convention (Z-X-Z) |
