bestie this is only part 1 of the page, so don't go anywhere — there's more coming and it's lowkey gonna be iconic. 🫶✨

💖 DETAILED DESCRIPTION 💖

okay bestie, so SoTextureCoordinate2 is literally just a container of coordinates for mapping 2D textures. that's it. that's the whole vibe. ✨

when traversal runs into nodes of this type, the coordinates inside get put on the state stack. some shape nodes — SoIndexedFaceSet is one of them, along with many others — can then grab those coordinates for explicit, detailed control of how textures get mapped onto their surfaces. you're the main character, you decide the mapping. 💅

and listen: if texturemapping is used without any SoTextureCoordinate2 nodes in the scenegraph leading up to a shape node, every shape type has default fallbacks. so you only actually need SoTextureCoordinate2 nodes if the default mapping isn't serving and you want something more custom. no cap.

heads up bestie 🫶 — an SoTextureCoordinate2 node will replace the coordinates already present in the state (if any). it doesn't stack politely, it takes over. periodt.

here's a very simple example (in Inventor scenegraph file format — mapping it to sourcecode is straightforward) showing how to set up two quadratic polygons, one mapped 1:1 to the texture, the other using only the upper left quarter of the texture:

Separator {
   Texture2 {
      image 6 8 3
      0x00ff0000 0x00ff0000 0x000000ff 0x000000ff 0x00ff00ff 0x00ff00ff
      0x00ff0000 0x00ff0000 0x000000ff 0x000000ff 0x00ff00ff 0x00ff00ff
      0x00ff0000 0x00ff0000 0x000000ff 0x000000ff 0x00ff00ff 0x00ff00ff
      0x0000ff00 0x0000ff00 0x0000ffff 0x0000ffff 0x0000ff00 0x0000ff00
      0x0000ff00 0x0000ff00 0x0000ffff 0x0000ffff 0x0000ff00 0x0000ff00
      0x00ffff00 0x00ffff00 0x000000ff 0x000000ff 0x00ffffff 0x00ffffff
      0x00ffff00 0x00ffff00 0x000000ff 0x000000ff 0x00ffffff 0x00ffffff
      0x00ffff00 0x00ffff00 0x000000ff 0x000000ff 0x00ffffff 0x00ffffff
   }

   Coordinate3 { point [ -1 -1 0, 1 -1 0, 1 1 0, -1 1 0 ] }

   # "1:1 mapping" to actual texture appearance. (Note that Y goes
   # from bottom to top, versus the common way of specifying bitmap
   # data from top to bottom.)
   TextureCoordinate2 { point [ 0 1, 1 1, 1 0, 0 0 ] }

   IndexedFaceSet {
      coordIndex [ 0, 1, 2, 3, -1 ]
      textureCoordIndex [ 0, 1, 2, 3, -1 ]
   }

   Translation { translation +4 0 0 }

   # Top left corner.
   TextureCoordinate2 { point [ 0 0.5, 0.5 0.5, 0.5 0, 0 0 ] }

   IndexedFaceSet {
      coordIndex [ 0, 1, 2, 3, -1 ]
      textureCoordIndex [ 0, 1, 2, 3, -1 ]
   }
}

🎀 CONSTRUCTOR & DESTRUCTOR DOCUMENTATION 🎀

SoTextureCoordinate2::SoTextureCoordinate2 (void )

Constructor. she's born. 👑

SoTextureCoordinate2::~SoTextureCoordinate2 () [protected], [virtual]

Destructor. she's resting. 💀 (it's protected and virtual, iykyk.)

✨ MEMBER FUNCTION DOCUMENTATION ✨

SoType SoTextureCoordinate2::getTypeId (void ) const [virtual]

Returns the type identification of an object derived from a class inheriting SoBase. this is what powers run-time type checking and "downward" casting. it's giving very important internals, lowkey.

Usage example:

void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}

for application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. this is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

for more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

const SoFieldData * SoTextureCoordinate2::getFieldData (void ) const [protected], [virtual]

Returns a pointer to the class-wide field data storage object for this instance. if there are no fields present, it returns NULL. fr fr.

Reimplemented from SoFieldContainer.

void SoTextureCoordinate2::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. the all-rounder. 💅

Reimplemented from SoNode.

void SoTextureCoordinate2::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

this gets called during rendering traversals. nodes influencing the rendering state in any way — or who want to throw geometry primitives at OpenGL — override this method. it's the one doing the actual visual slay. 🔥

Reimplemented from SoNode.

void SoTextureCoordinate2::callback (SoCallbackAction * action) [virtual]

Action method for SoCallbackAction.

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. very "here's what's going on, bestie" energy. 🦋

Reimplemented from SoNode.

void SoTextureCoordinate2::pick (SoPickAction * action) [virtual]

Action method for SoPickAction.

does common processing for SoPickAction action instances. who's there? it's the pick. 🙈

Reimplemented from SoNode.

🌸 MEMBER DATA DOCUMENTATION 🌸

SoMFVec2f SoTextureCoordinate2::point

The set of 2D texture coordinates. default value of the field is an empty set. literally nothing in there until you fill it. 🎀

texture coordinates are usually specified in normalized coordinates, ie in the range [0, 1]. (0, 0) is the lower left corner, while (1, 1) is the upper right corner of the texture image. coordinates outside the [0, 1] range can be used to repeat the texture across a surface. ✨
