DESCRIPTION
A field containing a single SbRotation (an arbitrary rotation).

SoSFRotations are written to file as four floating point values separated by whitespace. The 4 values represent an axis of rotation followed by the amount of right-handed rotation about that axis, in radians. For example, a 180 degree rotation about the Y axis is:

0 1 0  3.14159265

METHODS
void
getValue(const SbVec3f &axis, float &angle) const
Gets the value of the field as an axis/angle.

void
setValue(float q0, float q1, float q2, float q3)

setValue(float q[4])
Set the field to the given quaternion.

void
setValue(const SbVec3f &axis, float angle)
Set the field to the rotation given by axis/angle.

static SoType
getClassTypeId()
virtual void
getTypeId() const
Returns the type for this class or a particular object of this class.

const SbRotation &
getValue() const
Returns this field's value.

const SbRotation &
operator =(const SbRotation & newValue)
void
setValue(const SbRotation & newValue)
Sets this field to newValue.

int
operator ==(const SoSFRotation &f) const
int
operator !=(const SoSFRotation &f) const
Returns TRUE if f is of the same type and has the same value as this field.
