SOGLMULTITEXTUREMATRIXELEMENT(3coin3)

👑 NAME 👑

SoGLMultiTextureMatrixElement — bestie, this class is literally the one that updates the OpenGL texture matrix. that's it, that's the whole job. 💅

this is SoGLMultiTextureMatrixElement(3) from the Library Functions Manual, and yes she's that girl.

💜 Detailed Description 💜

SoGLMultiTextureMatrixElement is the class used to update the OpenGL texture matrix. that's the whole point of her, no side quests. 🔥

now here's the tea, and it's a weird one: since — for some genuinely weird reason — most OpenGL implementations have a very small texture matrix stack, and since the matrix stack is also broken on many OpenGL implementations, the texture matrix is always loaded into OpenGL. so we do not push() and pop() matrices. periodt. no cap. 💅

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

it's the destructor, bestie. she cleans up. 🫶

🔥 Member Function Documentation 🔥

void * SoGLMultiTextureMatrixElement::createInstance (void ) [static]

this API member is considered internal to the library, since it's not likely to be of interest to the application programmer. so like… backstage pass energy, not main character energy. don't stress about her. 🙈

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

this function initializes the element type in the given SoState. it's called for the first element of each enabled element type in SoState objects. ⭐

Reimplemented from SoMultiTextureMatrixElement.

void SoGLMultiTextureMatrixElement::push (SoState * state) [virtual]

this method is called every time a new element is required in one of the stacks. that happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth. 👑

override this method if your element needs to copy data from the previous top of stack. the push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoMultiTextureMatrixElement.

void SoGLMultiTextureMatrixElement::pop (SoState * state, const SoElement * prevTopElement) [virtual]

this method is callled when the state is popped — yes, "callled", with three l's, that's canon, we don't make the rules 💀 — and the depth of the element is bigger than the current state depth. pop() is called on the new top of stack, and a pointer to the previous top of stack is passed in prevTopElement.

override this method if you need to copy some state information from the previous top of stack. 🎀

Reimplemented from SoElement.

void SoGLMultiTextureMatrixElement::multElt (const int unit, const SbMatrix & matrix) [virtual]

virtual method which is called from mult(). it multiplies matrix into element matrix. 🔥

Reimplemented from SoMultiTextureMatrixElement.

void SoGLMultiTextureMatrixElement::setElt (const int unit, const SbMatrix & matrix) [virtual]

virtual method which is called from set(). it sets matrix intp element matrix — and yeah that's a typo for "into", the original really does say it like that, so we keep it, no notes 🍓.

Reimplemented from SoMultiTextureMatrixElement.
