💜 Detailed Description 💜

The SoProjectionMatrixElement class is yet to be documented.

FIXME: write doc. 😭 bestie the docs are literally unfinished, we're all just vibing on faith here

🍓 Constructor & Destructor Documentation 🍓

SoProjectionMatrixElement::~SoProjectionMatrixElement (void ) [protected], [virtual]

Destructor. 💀 it's giving goodbye, it's giving cleanup, it's giving protected so only the family can call it

🌸 Member Function Documentation 🌸

SoType SoProjectionMatrixElement::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. 🎀 it's the ✨identity✨ girlie of the whole class

int SoProjectionMatrixElement::getClassStackIndex (void ) [static]

This static method returns the state stack index for the class. 👑 your seat number in the state stack, lowkey iconic

void * SoProjectionMatrixElement::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. 🦋 (so like, if you're an app dev, this one's not for you bestie, no offense, it's just ✨internal business✨)

void SoProjectionMatrixElement::initClass (void ) [static]

Initialize relevant common data for all instances, like the type system. 🌟 setting the whole squad up before the party starts, fr fr

void SoProjectionMatrixElement::init (SoState * state) [virtual]

Initializes the element to its default value. The default value for projectionMatrix is the identity matrix. 💅 (identity matrix = the "I'm not like other matrices" matrix, it's giving main character energy, it changes nothing and that's the point)

Reimplemented from SoReplacedElement.

void SoProjectionMatrixElement::set (SoState *const state, SoNode *const node, const SbMatrix & projectionMatrix) [static]

Sets the current projection matrix to matrix. 🎀 boom, new matrix, who dis

const SbMatrix & SoProjectionMatrixElement::get (SoState *const state) [static]

Returns the current projection matrix. 🔥 hand it over bestie, we need to see it

void SoProjectionMatrixElement::setElt (SbMatrix const & matrix) [protected], [virtual]

virtual method which is called from the static method set(). Sets element projection matrix to matrix. 👀 so set() calls setElt(), it's giving delegation, it's giving teamwork, we love to see it

Reimplemented in SoGLProjectionMatrixElement.
