💖 Detailed Description 💖

The SoTextureMatrixTransform class is used to define a texture matrix transformation. yes, again, that's literally her whole job and she's slaying it 🎀

Textures applied to shapes in the scene can be transformed by "prefixing" in the state with instances of this node type. so you stack her up in the scene graph and she rewrites how the texture sits on your shapes. main character energy fr fr ✨

⚠️ Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API. so like, if you're porting old Inventor code, don't come crying to her, she was never invited to that party 😭

FILE FORMAT/DEFAULTS:

TextureMatrixTransform {
    matrix
      1 0 0 0
      0 1 0 0
      0 0 1 0
      0 0 0 1
}

🌟 Constructor & Destructor Documentation 🌟

🎀 SoTextureMatrixTransform::SoTextureMatrixTransform (void ) 🎀

Constructor. that's the whole description, she keeps it short and sweet 💅

🎀 SoTextureMatrixTransform::~SoTextureMatrixTransform () [protected], [virtual] 🎀

Destructor. protected, virtual, iconic. rest in peace bestie 🫶

SoType SoTextureMatrixTransform::getClassTypeId (void ) — static ✨

okay so this one is a static method and it literally just hands you back the SoType object that's associated with objects of this class. that's it. that's the whole vibe. 💅

SoType SoTextureMatrixTransform::getTypeId (void ) const — virtual 🦋

gives you the type identification of an object that's derived from a class inheriting SoBase. bestie, this is the runtime type checking + "downward" casting machinery. it's how the library figures out what tf it's actually looking at while everything's running. 👑

  • Implements SoBase.

const SoFieldData ** SoTextureMatrixTransform::getFieldDataPtr (void ) — static, protected 🙈

so this API member is considered internal to the library — meaning it's not likely to be of interest to the application programmer. like, not me gatekeeping but also kind of me gatekeeping. it's giving "staff only" door. 🚪

Returns the SoFieldData class which holds information about fields in this node.

const SoFieldData * SoTextureMatrixTransform::getFieldData (void ) const — protected, virtual 🌸

returns a pointer to the class-wide field data storage object for this instance. and if there are no fields present? returns NULL. no fields, no pointer, that's the rule. 🫶

  • Reimplemented from SoFieldContainer.

void SoTextureMatrixTransform::doAction (SoAction * action) — virtual 💫

this function performs the typical operation of a node for any action. generic queen behavior honestly.

  • Reimplemented from SoNode.

void SoTextureMatrixTransform::callback (SoCallbackAction * action) — virtual 🎀

action method for SoCallbackAction.

it simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph. lowkey so useful.

  • Reimplemented from SoNode.

void SoTextureMatrixTransform::GLRender (SoGLRenderAction * action) — virtual 🔥

action method for the SoGLRenderAction.

this is called during rendering traversals. any node that influences the rendering state in any way, or wants to throw geometry primitives at OpenGL, overrides this method. main character energy fr fr.

  • Reimplemented from SoNode.

void SoTextureMatrixTransform::getMatrix (SoGetMatrixAction * action) — virtual 🌈

action method for SoGetMatrixAction.

updates action by accumulating with the transformation matrix of this node (if any). "if any" — because sometimes there just isn't one, and that's okay. ⭐

  • Reimplemented from SoNode.

void SoTextureMatrixTransform::pick (SoPickAction * action) — virtual 🍓

action method for SoPickAction.

does common processing for SoPickAction action instances. the shared chores of picking, handled. 🧚

  • Reimplemented from SoNode.

📦 Member Data Documentation 📦

SoSFMatrix SoTextureMatrixTransform::matrix 💜

texture coordinate matrix. default is the identity matrix. so if you don't touch it, it's literally doing nothing to your tex coords — which is, honestly, the correct and iconic default. ✨
