Detailed Description¶
The SoSFRotation class is a container for an SbRotation. This field is used where nodes, engines or other field containers needs to store a single rotation definition.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:

Member Function Documentation¶
SoType SoSFRotation::getClassTypeId (void) [static]¶
Returns a unique type identifier for this field class. See Also:getTypeId(), SoType
SoType SoSFRotation::getTypeId (void) const [virtual]¶
Returns the type identification instance which uniquely identifies the Coin field class the object belongs to. See Also:getClassTypeId(), SoType
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. Reimplemented from SoSField.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 floatq0, const floatq1, const floatq2, const floatq3)¶
Set the rotation from a set of quaternion values.void SoSFRotation::setValue (const floatq[4])¶
Set the rotation from a set of quaternion values.void SoSFRotation::setValue (const SbVec3f &axis, const floatangle)¶
Set the rotation from an axis and an angle around this axis.Author¶
