# move (Aero.Node)

Change node translation and rotation

## Syntax

```move(h,translation,rotation) h.move(translation,rotation) ```

## Description

`move(h,translation,rotation)` and `h.move(translation,rotation)` set a new position and orientation for the node object `h`. `translation` is a 1-by-3 matrix in the aerospace body x-y-z coordinate system or another coordinate system. In the latter case, you can use the `CoordTransformFcn` function to move it into an aerospace body. The defined aerospace body coordinate system is defined relative to the screen as x-left, y-in, z-down.

`rotation` is a 1-by-3 matrix specified as an Euler angle, in radians, that specifies the rotations about the right-hand x-y-z coordinate axes. The order of application of the rotation is z-y-x (yaw, pitch, and roll (Y-P-R)). This function uses the `CoordTransformFcn` to apply the translation and rotation from the input coordinate system to the aerospace body. The function then moves the translation and rotation from the aerospace body to the VRML x-y-z coordinates. The defined VRML coordinate system is defined relative to the screen as x-right, y-up, z-out.

## Examples

collapse all

Use the Simulink® 3D Animation™ `vrnode/getfield` function to retrieve the translation and rotation. These coordinates are those used in the animation software.

```h = Aero.VirtualRealityAnimation; h.VRWorldFilename = 'asttkoff.wrl'; h.initialize();```

```newtrans = getfield(h.Nodes{2}.VRNode,'translation') - [0 40 6]; newrot = [0.4 0.3 0.1]; h.Nodes{2}.move(newtrans,newrot);```

## Limitations

This function cannot get the node position in aerospace body coordinates; it needs to use the `CoordTransformFcn` to do so.

This function cannot set a viewpoint position or orientation (see `addViewpoint`).
