Each set of 4 values is an axis of rotation followed by the amount of right-handed rotation about that axis, in radians. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example: ``` [ 1 0 0 0, -.707 -.707 0 1.57 ] ``` ## METHODS **void** **set1Value(int index, const SbVec3f &axis, float angle)**\ Sets the **index**'th value to the given axis/angle. **void** **setValue(const SbVec3f &axis, float angle)**\ Makes this field have exactly one value, given by **axis** and **angle**. **void** **set1Value(int index, float q0, float q1, float q2, float q3)**\ **void** **set1Value(int index, const float q\[4\])**\ Sets the **index**'th value to the given quaternion. **void** **setValue(float q0, float q1, float q2, float q3)**\ **void** **setValue(float q\[4\])**\ Makes this field have exactly one value, given by the quaternion. **static SoType** **getClassTypeId()**\ **virtual void** **getTypeId() const**\ Returns the type for this class or a particular object of this class. **const SbRotation &** **operator \[\](int i) const**\ Returns the **i**'th value of the field. Indexing past the end of the field (passing in **i** greater than **getNum()**) will return garbage. **const SbRotation \*** **getValues(int start) const**\ Returns a pointer into the array of values in the field, starting at index **start**. The values are read-only; see the **startEditing()**/**finishEditing()** methods for a way of modifying values in place. **int** **find(const SbRotation & targetValue, SbBool addIfNotFound = FALSE)**\ Finds the given value in the array and returns the index of that value in the array. If the value is not found, -1 is returned. If **addIfNotFound** is set, then **targetValue** is added to the end of the array (but -1 is still returned). **void** **setValues(int start, int num, const SbRotation \*newValues)**\ Sets **num** values starting at index **start** to the values in **newValues**. The array will be automatically be made larger to accomodate the new values, if necessary. **void** **set1Value(int index, const SbRotation & newValue)**\ Sets the **index**'th value in the array to **newValue**. The array will be automatically expanded, if necessary. **const SbRotation &** **operator =(const SbRotation & newValue)**\ **void** **setValue(const SbRotation & newValue)**\ Sets the first value in the array to **newValue**, and deletes the second and subsequent values. **int** **operator ==(const SoMFRotation &f) const**\ **int** **operator !=(const SoMFRotation &f) const**\ Returns TRUE if all of the values of this field equal (do not equal) those of the given field. If the fields are different types FALSE will always be returned (even if one field is an **SoMFFloat** with one value of 1.0 and the other is an **SoMFInt** with a value of 1, for example). **SbRotation \*** **startEditing()**\ **void** **finishEditing()**\ **startEditing()** returns a pointer to the internally-maintained array that can be modified. The values in the array may be changed, but values cannot be added or removed. It is illegal to call any other editing methods between **startEditing()** and **finishEditing()** (e.g. **set1Value()**, **setValue()**, etc). Fields, engines or sensors connected to this field and sensors are not notified that this field has changed until **finishEditing()** is called. Calling **finishEditing()** always sets the **isDefault()** flag to FALSE and informs engines and sensors that the field changed, even if none of the values actually were changed. ## SEE ALSO **SbRotation**
