## DESCRIPTION

**The SoShuttle** class is derived from **SoTranslation**, so it applies a translation to the current transformation. Using engines connected to the **realTime** global field, the translation value is animated over time between two fixed translations, achieving a shuttling effect. The period of the motion can be adjusted by changing the **speed** field. The current translation at any time is available in the **translation** field, inherited from **SoTranslation**

## FIELDS

**SoSFVec3f**	**translation0**\
 **SoSFVec3f**	**translation1**\
 These define the two fixed translations that are interpolated to create the shuttling motion.

**SoSFFloat**	**speed**\
 Defines the speed of the shuttle, in cycles per second.

**SoSFBool**	**on**\
 Allows applications to enable or disable the motion easily.

## METHODS

	**SoShuttle()**\
 Creates a shuttle node with default settings.

**static SoType**	**getClassTypeId()**\
 Returns type identifier for this class.

## ACTION BEHAVIOR

**SoGLRenderAction, SoCallbackAction, SoGetBoundingBoxAction, SoRayPickAction**\
 Concatenates interpolated translation value with the current transformation matrix.

**SoGetMatrixAction**\
 Returns transformation matrix specified by the interpolated translation.

## FILE FORMAT/DEFAULTS

```
Shuttle {
translation	0 0 0
translation0	0 0 0
translation1	0 0 0
speed	1
on	TRUE
}
```
