This field is used where nodes, engines or other field containers need to store a single rotation definition. Fields of this type stores their value to file as a rotation axis vector plus a rotation angle: 'axis0 axis1 axis2 angle'. Note that there is one very common mistake that is easy to make when setting the value of an SoSFRotation field, and that is to inadvertently use the wrong SbRotation constructor. This example should clarify the problem: mytransformnode->rotation.setValue(0, 0, 1, 1.5707963f); The programmer clearly tries to set a PI/2 rotation around the Z axis, but this will fail, as the SbRotation constructor invoked above is the one that takes as arguments the 4 floats of a quaternion. What the programmer almost certainly wanted to do was to use the SbRotation constructor that takes a rotation vector and a rotation angle, which is invoked like this: mytransformnode->rotation.setValue(SbVec3f(0, 0, 1), 1.5707963f); See also SoMFRotation Member Function Documentation void * SoSFRotation::createInstance (void) [static] This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Creates a new instance of the class type corresponding to the SoType object. SoType SoSFRotation::getClassTypeId (void) [static] This static method returns the SoType object associated with objects of this class. SoType SoSFRotation::getTypeId (void) const [virtual] Returns the type identification of an object derived from a class inheriting SoField. This is used for runtime type checking and 'downward' casting. Implements SoField. void SoSFRotation::copyFrom (const SoField & f) [virtual] Copy value(s) from f into this field. f must be of the same type as this field. Implements SoField. SbBool SoSFRotation::isSame (const SoField & f) const [virtual] Check for equal type and value(s). Implements SoField. void SoSFRotation::initClass (void) [static] Internal method called upon initialization of the library (from SoDB::init()) to set up the type system. void SoSFRotation::getValue (SbVec3f & axis, float & angle) const Return value of rotation as an axis and an angle around this axis. void SoSFRotation::setValue (const float q0, const float q1, const float q2, const float q3) Set the rotation from a set of quaternion values. void SoSFRotation::setValue (const float q[4]) Set the rotation from a set of quaternion values. void SoSFRotation::setValue (const SbVec3f & axis, const float angle) Set the rotation from an axis and an angle around this axis.
