🫶 ok bestie that's the end of part 1 — there's more coming, so don't go anywhere 💅

✨ DETAILED DESCRIPTION ✨

So the SoVRMLPixelTexture class is literally just here to map a texture image onto geometry. that's the whole job bestie 💅

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

PixelTexture {
  exposedField SFImage  image      0 0 0    # see SoSFImage
  field        SFBool   repeatS    TRUE
  field        SFBool   repeatT    TRUE
}

The PixelTexture node defines a 2D image-based texture map as an explicit array of pixel values (the image field) and parameters controlling tiling repetition of the texture onto geometry. Texture maps are defined in a 2D coordinate system (s, t) that ranges from 0.0 to 1.0 in both directions. The bottom edge of the pixel image corresponds to the S-axis of the texture map, and left edge of the pixel image corresponds to the T-axis of the texture map. The lower-left pixel of the pixel image corresponds to s=0.0, t=0.0, and the top-right pixel of the image corresponds to s = 1.0, t = 1.0. See 4.6.11, Texture maps (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.6.11), for a general description of texture maps. Figure 6.13 depicts an example PixelTexture. 🦋

Figure 6.13 -- PixelTexture node

See 4.14, Lighting model (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.14), for a description of how the texture values interact with the appearance of the geometry. SoSFImage, describes the specification of an image. The repeatS and repeatT fields specify how the texture wraps in the S and T directions. If repeatS is TRUE (the default), the texture map is repeated outside the 0-to-1 texture coordinate range in the S direction so that it fills the shape. If repeatS is FALSE, the texture coordinates are clamped in the S direction to lie within the 0.0 to 1.0 range. The repeatT field is analogous to the repeatS field. 🎀

🌸 CONSTRUCTOR & DESTRUCTOR DOCUMENTATION 🌸

SoVRMLPixelTexture::SoVRMLPixelTexture (void )

Constructor. the origin story, the birth, the main character entrance 👑

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

Destructor. it's giving farewell tour 😭

💖 MEMBER FUNCTION DOCUMENTATION 💖

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

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and "downward" casting. no cap, this is how you safely figure out what you're actually holding 🔍

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.

Reimplemented from SoVRMLTexture.

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

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL. ✨

Reimplemented from SoVRMLTexture.

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

This function performs the typical operation of a node for any action. it does the thing, for literally any action, it's so versatile 💅

Reimplemented from SoNode.

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

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method. yeah, it's throwing hands (and geometry) at OpenGL 🔥

Reimplemented from SoVRMLTexture.

void SoVRMLPixelTexture::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. free info, we love to see it 🫶

Reimplemented from SoNode.

void SoVRMLPixelTexture::rayPick (SoRayPickAction * action) [virtual]

Action method for SoRayPickAction.

Checks the ray specification of the action and tests for intersection with the data of the node. did somebody say raycast? say less 🌈

Nodes influencing relevant state variables for how picking is done also overrides this method.

Reimplemented from SoNode.

SbBool SoVRMLPixelTexture::readInstance (SoInput * in, unsigned short flags) [protected], [virtual]

This method is mainly intended for internal use during file import operations.

It reads a definition of an instance from the input stream in. The input stream state points to the start of a serialized / persistant representation of an instance of this class type.

TRUE or FALSE is returned, depending on if the instantiation and configuration of the new object of this class type went ok or not. The import process should be robust and handle corrupted input streams by returning FALSE.

flags is used internally during binary import when reading user extension nodes, group nodes or engines.

Reimplemented from SoNode.

void SoVRMLPixelTexture::notify (SoNotList * list) [protected], [virtual]

Overloaded to detect when fields change. it's watching. it's always watching 👀

Reimplemented from SoNode.
