🌸 Detailed Description 🌸

SoSFRotation is a container for an SbRotation. It’s the field you reach for when nodes, engines, or other field containers need to store a single rotation definition. 🎀

Fields of this type store their value to file as a rotation axis vector plus a rotation angle: "axis0 axis1 axis2 angle".

Okay so there is one very common mistake that is easy to make when setting the value of an SoSFRotation field: accidentally using the wrong SbRotation constructor. Not me doing a vibe check on your code, but 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);

🔥 Member Function Documentation 🔥

✨ 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.

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::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.
