## Detailed Description

The **SoMotion3Event** class contains information about 3D movement events.

Motion3 events are generated by devices capable of "3D motion", for instance a spaceball device. Instances of this class contain information about these devices' translations and rotations in all 3 dimensions.

## Constructor & Destructor Documentation

### SoMotion3Event::SoMotion3Event (void )

Constructor. Resets values for translation and rotation information.

### SoMotion3Event::~SoMotion3Event () \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoMotion3Event::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### SoType SoMotion3Event::getTypeId (void ) const \[virtual\]

Returns the type identification of an object derived from a class inheriting **SoEvent**. This is used for runtime type checking and "downward" casting.

Reimplemented from **SoEvent**.

### void SoMotion3Event::initClass (void ) \[static\]

Initialize the type information data.

### void SoMotion3Event::setTranslation (const SbVec3f & t)

Sets the translation value of this event. Method is used by the window specific device class(es) generating the event.

**See also**

**getTranslation()**

### const SbVec3f & SoMotion3Event::getTranslation (void ) const

Returns translation value. Note that translation are specified relative to former events, i.e. the values given here are *not* accumulated global coordinates.

**See also**

**getTime()**

### void SoMotion3Event::setRotation (const SbRotation & r)

Sets the rotation value of this event. Method is used by the window specific device class(es) generating the event.

### const SbRotation & SoMotion3Event::getRotation (void ) const

Returns rotational value. Note that rotations are specified relative to former events, i.e. the values given here are *not* accumulated rotations.

**See also**

**getTime()**
