SoTextureMatrixElement(3)

✨ SoTextureMatrixElement(3) ✨

okay bestie, welcome to the Coin manual, section 3, and today's main character is SoTextureMatrixElement 💅 she lives in the library functions and she is obsessed with one thing: managing the texture matrix stack. like that's her whole job. no cap.

🌟 Detailed Description 🌟

The SoTextureMatrixElement class is used to manage the texture matrix stack. that's her. that's the whole girlboss job description fr fr.

so what does a texture matrix even do, bestie? it transforms texture coordinates before they get used to map textures onto polygons. like the glow-up happens first, then the texture lands on the polygon. slay. ✨

🎀 Constructor & Destructor Documentation 🎀

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

the destructor. she's leaving, say bye 👋💜

💅 Member Function Documentation 💅

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

so this API member is considered internal to the library, because it's not likely to be of any interest to the application programmer. iykyk. you probably don't need her, and that's okay 🫶

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

this function initializes the element type in the given SoState. it gets called for the first element of each enabled element type in SoState objects. like the opening number. iconic.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLTextureMatrixElement.

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

this method is called every single time a new element is required in one of the stacks. when does that happen? 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. so basically whenever the stack needs a fresh one 💅

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 SoAccumulatedElement.

void SoTextureMatrixElement::makeIdentity (SoState *const state, SoNode *const node) [static]

sets the current texture matrix to identity. that's the reset button, bestie ✨

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

sets the current texture matrix to matrix.

this method is an extension versus the Open Inventor API. so like, she's extra. not in the original. noted 📝

void SoTextureMatrixElement::mult (SoState *const state, SoNode *const node, const SbMatrix & matrix) [static]

multiplies matrix into the current texture matrix.

void SoTextureMatrixElement::translateBy (SoState *const state, SoNode *const node, const SbVec3f & translation) [static]

appends translation to the current texture matrix. scoot scoot 🦋

void SoTextureMatrixElement::rotateBy (SoState *const state, SoNode *const node, const SbRotation & rotation) [static]

appends rotation to the current texture matrix. spin, bestie, spin 🌪️

void SoTextureMatrixElement::scaleBy (SoState *const state, SoNode *const node, const SbVec3f & scaleFactor) [static]

appends scaleFactor to the current texture matrix. glow-up unlocked 📈

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

returns the current texture matrix. she's giving what you asked for 💖

void SoTextureMatrixElement::emptyMatrix (SoState *const state) [static]

provided for API compatibility only. does nothing for the moment. so she's literally just standing there. existing. not doing a thing. queen behavior honestly 💀

void SoTextureMatrixElement::makeEltIdentity (void ) [protected], [virtual]

virtual method which is called from makeIdentity(). sets the element matrix to identity.

Reimplemented in SoGLTextureMatrixElement.

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

virtual method which is called from set(). sets the texture matrix to matrix.

this method is an extension versus the Open Inventor API. again! she's extra, twice 🌟

Reimplemented in SoGLTextureMatrixElement.

void SoTextureMatrixElement::multElt (const SbMatrix & matrix) [protected], [virtual]

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

Reimplemented in SoGLTextureMatrixElement.

void SoTextureMatrixElement::translateEltBy (const SbVec3f & translation) [protected], [virtual]

virtual method which is called from translateBy(). appends translation to the element matrix.

Reimplemented in SoGLTextureMatrixElement.

void SoTextureMatrixElement::rotateEltBy (const SbRotation & rotation) [protected], [virtual]

virtual method which is called from rotateBy(). appends rotation to the element matrix.

Reimplemented in SoGLTextureMatrixElement.

void SoTextureMatrixElement::scaleEltBy (const SbVec3f & scaleFactor) [protected], [virtual]

virtual method which is called from scaleBy(). appends scaleFactor to the element matrix.

Reimplemented in SoGLTextureMatrixElement.

const SbMatrix & SoTextureMatrixElement::getElt (void ) const [protected], [virtual]

returns the element matrix. called from get().

so yeah, this whole page is from Coin, Version 3.1.3, and that's the whole manual page for SoTextureMatrixElement(3) — take care of her, she manages a whole stack for you and she asks for nothing in return 💖✨🎀 bye bestie!!
