🔥 Detailed Description 🔥

okay so. the SoVertexShader class is used for setting up vertex shader programs. that's the whole assignment, and it ate. 💅

if you want the full tea on how to set up a scene graph with shaders, go read Shaders in Coin — it's right there for you.

🎀 FILE FORMAT/DEFAULTS 🎀

VertexShader {
  isActive TRUE
  sourceType FILENAME
  sourceProgram ""
  parameter []
}

Coin 2.5. yeah bestie, this one's been iconic for a minute. ✨

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

okay bestie, this one is literally the "who dis??" check for any object that inherits from SoBase. It hands you back the type identification of the object, and it's what makes run-time type checking and "downward" casting possible. No cap, it's the backbone of Coin's whole type system. 🫶

Usage example, straight up:

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

Now for my application programmers who wanna extend the library with new nodes, engines, nodekits, draggers or whatever else — listen up, because this is important: this method needs to be overridden in all subclasses. Periodt. It'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 — with SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes
• Inventor/engines/SoSubEngine.h — for engine classes
• and so on 💅

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

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

This one returns a pointer to the class-wide field data storage object for this instance. That's it, that's the whole vibe. 🎀

And if there are no fields present? It returns NULL. Simple as.

SbBool SoVertexShader::isSupported (SourceType sourceType) [static]

Returns a boolean indicating whether the requested source type is supported by the OpenGL driver or not. Slay, a yes-or-no answer. ✨

⚠️ Beware: to get a correct answer, a valid OpenGL context must be available. No context, no truth. Don't come for me when it lies to you. 😭
