💖 Detailed Description 💖

SoIndexedShape is the superclass for all indexed vertex shapes. 👑

It's an abstract class — so like, you don't instantiate it directly, bestie, it's giving "template" energy. What it does have is storage for four fields: the indices pointing at coordinates, normals, materials and texture coordinates, all sitting there for its subclasses to use. 🎀

🎀 Constructor & Destructor Documentation 🎀

`SoIndexedShape::SoIndexedShape (void ) [protected]`

Constructor. 🍼

`SoIndexedShape::~SoIndexedShape () [protected], [virtual]`

Destructor. 🪦

🔥 Member Function Documentation 🔥

`SoType SoIndexedShape::getTypeId (void ) const [virtual]`

Returns the type identification of an object derived from a class inheriting SoBase. This is what you use for run-time type checking and "downward" casting. 🕵️‍♀️

Usage example:

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

Okay so for all the application programmers out there who wanna extend the library with new nodes, engines, nodekits, draggers or whatever else: this method needs to be overridden in all subclasses. That's 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. iykyk 🫶

For more info on writing Coin extensions, go look at the class documentation of the toplevel superclasses for the various class groups.

Reimplemented from SoVertexShape.

Reimplemented in SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, and SoIndexedTriangleStripSet.

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

Hands you back a pointer to the class-wide field data storage object for this instance. And if there are no fields present? It returns NULL. Simple as that. 💅

Reimplemented from SoVertexShape.

Reimplemented in SoIndexedFaceSet, SoIndexedLineSet, SoIndexedMarkerSet, SoIndexedPointSet, and SoIndexedTriangleStripSet.

`void SoIndexedShape::computeBBox (SoAction * action, SbBox3f & box, SbVec3f & center) [protected], [virtual]`

This one is implemented by SoShape subclasses so the SoShape superclass can know the exact size and weighted center point of the shape's bounding box. 📦

The bounding box and center point should be calculated and returned in the local coordinate system. Noted.

The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It gets invoked from SoShape::getBoundingBox(). (And heads up: subclasses should not override SoNode::getBoundingBox().) 🙅‍♀️

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry. So don't go reading it before you write it, bestie.

Implements SoShape.

`int SoIndexedShape::getNumVerts (const int startCoord) [protected]`

Starting at index position startCoord, this returns the number of indices until either the end of the index array or a separator index (-1). Whichever comes first. 🏁

`void SoIndexedShape::setupIndices (const int numParts, const int numFaces, const SbBool needNormals, const SbBool needTexCoords) [protected]`

Not implemented. Probably only used for internal purposes in SGI's original Open Inventor, which means it should have been private. 😭

Let us know if you need this method for any code you are porting and we'll look into implement it properly. 🫶

`const int32_t * SoIndexedShape::getNormalIndices (void ) [protected]`

Let us know if you need this method for any code you are porting and we'll look into implement it properly. 🫶

`SbBool SoIndexedShape::areTexCoordsIndexed (SoAction * action) [static], [protected]`

Returns whether texture coordinates should be indexed or not. 🧵

`SbBool SoIndexedShape::getVertexData (SoState * state, const SoCoordinateElement & coords, const SbVec3f & normals, const int32_t & cindices, const int32_t & nindices, const int32_t & tindices, const int32_t & mindices, int & numcindices, const SbBool needNormals, SbBool & normalCacheUsed) [protected]`

A convenience method that will fetch the data needed for rendering or generating primitives. It takes care of the normal cache too, so you don't gotta. ✨

This method was not part of the original SGI Open Inventor API — it's an extension specific for Coin. 🪙
