💖 SoSFRotation 💖 — the Coin manual page, but make it cute

okay bestie, sit down, hydrate, and let's talk about SoSFRotation(3) — that's section 3 of the Coin manual, and yes it's giving "I am a tiny container class and I will change your whole 3D scene" energy. 🎀

✨ NAME ✨

SoSFRotation — the class that is literally just a container for an SbRotation. one (1) rotation. that's the whole job. slay. 💅

🦋 SYNOPSIS 🦋

#include <Inventor/fields/SoSFRotation.h>

Inherits SoSField. yes bestie, it's a whole family tree situation. 🌳

🌈 Detailed Description 🌈

okay so. the SoSFRotation class is a container for an SbRotation. that's it. that's the tweet. 🐦

this field is used where nodes, engines or other field containers need to store a single rotation definition. one rotation. no more, no less. main character energy but make it minimal. 💅

Fields of this type stores their value to file as a rotation axis vector plus a rotation angle: "axis0 axis1 axis2 angle". no cap.

⚠️ bestie listen to me very carefully. 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);

like... the way that 0, 0, 1, 1.5707963f looks right and is so wrong. it's giving quaternion jumpscare. 😭 please use the SbVec3f version. i'm begging. 🫶

🛠️ 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. (so like... not for you bestie, but okay go off 👑)

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. it's the class's little name tag. 🏷️

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. no mixing, no matching, we're not doing that today. 🙅

Implements SoField.

SbBool SoSFRotation::isSame (const SoField & f) const [virtual]

Check for equal type and value(s). vibe check, but for fields. ✅

Implements SoField.

void SoSFRotation::initClass (void ) [static]

Internal method called upon initialization of the library (from SoDB::init()) to set up the type system. it's backstage work, you don't see it, but the show doesn't happen without it. 🎭

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. (remember the jumpscare above, bestie — this is that constructor's friend 🫣)

void SoSFRotation::setValue (const float q[4])

Set the rotation from a set of quaternion values. same deal, but as an array. iconic of it.

void SoSFRotation::setValue (const SbVec3f & axis, const float angle)

Set the rotation from an axis and an angle around this axis. this is the one. this is the good one. use this one. 🫶✨

so yeah, that's the whole page bestie. no notes, 10/10, would rotate again. 🌸🦋💅
