💖 Detailed Description 💖

The SoTextureCoordinate2 class is literally your bestie for holding a whole set of coordinates that map 2D textures. When traversal hits a node of this type, the coordinates it carries get put on the state stack. Then some shape nodes (like SoIndexedFaceSet, and many others, no cap) can use those coordinates for explicit, detailed control over how textures get mapped onto their surfaces. It's giving full customization energy. ✨

(If texture mapping is used without any SoTextureCoordinate2 nodes in the scene graph leading up to a shape node, all shape types have default fallbacks. So SoTextureCoordinate2 nodes are only necessary if you're not satisfied with the default mapping. lowkey optional until you want to slay. 💅)

⚠️ heads up bestie: an SoTextureCoordinate2 node will replace the coordinates already present in the state (if any). no takebacks, it's a full swap. 🫶

Here's a very simple example (in Inventor scene graph file format -- mapping it to source code is straightforward) that shows 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
          }

          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. it's literally the birth of your node, bestie. ✨

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

Destructor. it's the goodbye era, protected and virtual, very demure. 💅

💅 Member Function Documentation 💅

SoType SoTextureCoordinate2::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. it's the class ID flex, iykyk. 👑

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

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting. Implements SoBase. it's giving RTTI but make it cute. 🦋

const SoFieldData ** SoTextureCoordinate2::getFieldDataPtr (void ) [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer. Returns the SoFieldData class which holds information about fields in this node. lowkey not your business but here it is. 🙈

const SoFieldData * SoTextureCoordinate2::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 SoFieldContainer. no fields? NULL. periodt. 💀

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

This function performs the typical operation of a node for any action. Reimplemented from SoNode. it's the main character action handler. 🌟

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

Action method for the SoGLRenderAction. This is called during rendering traversals. Nodes influencing the rendering state in any way or want to throw geometry primitives at OpenGL override this method. Reimplemented from SoNode. it's giving OpenGL drama, and we love that. 🔥

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. Reimplemented from SoNode. callback era, very useful. ✨

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

Action method for SoPickAction. Does common processing for SoPickAction action instances. Reimplemented from SoNode. picking things, iconic. 👑

🌸 Member Data Documentation 🌸

SoMFVec2f SoTextureCoordinate2::point

The set of 2D texture coordinates. Default value of field is an empty set. Texture coordinates are usually specified in normalized coordinates, i.e. 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. it's giving UV mapping realness. 🎀
