💫 DESCRIPTION 💫

okay so listen 🫶 — this node is the abstract base class for every vertex-based shape that ISN'T built from indices. The iconic trio of examples: SoFaceSet, SoLineSet, and SoQuadMesh. no cap 💅

Every single subclass of SoNonIndexedShape builds its objects using the coordinates that live in the vertexProperty field (that's the one it inherited from SoVertexShape, iykyk), or else it just grabs the current inherited coordinates. And the startIndex field — the one this very class defines? Yeah, it's obsolete now. It's only hanging around here for compatibility with ancient files and programs. it's giving legacy code energy fr fr 😭

The subclass is the one who decides what to do with this coordinate and any that come after it. The shape gets drawn with the current lighting model and drawing style, and it's transformed by the current transformation matrix. main character behavior honestly ✨

Now for the important part, bestie — material, normal, and texture coordinate bindings for shapes derived from this class ignore any index specifications. Like, a binding value of PER_FACE_INDEXED gets treated exactly the same way as PER_FACE, and so on down the line. it simply does not care 💀

And if there aren't enough values in the current coordinates, material, or texture coordinates? Errors will occur. Not a vibe check, an actual error. be careful 🌸

🌸 FIELDS 🌸

• SoSFInt32 startIndex — the obsolete field, kept around purely for compatibility reasons, periodt. It's the index of the first coordinate of the shape. she's retired but still on the payroll 🙈

🎀 METHODS 🎀

• static SoType getClassTypeId() — returns the type identifier for this class. your girl's official ID card 💅

🦋 FILE FORMAT/DEFAULTS 🦋

This is an abstract class, so there's nothing to show here — go peek at the reference page of a derived class if you want the format and the default values. she's abstract, she doesn't do defaults ✨
