SoComposeVec2f(3)

📦 version 3.1.3, in fedora 43, fedora 44

okay bestie, welcome to the SoComposeVec2f(3) manual page 💅 this is literally the glow-up you need to understand how to compose 2D vectors from two floats. no cap. let's get into it.

✨ NAME ✨

  • SoComposeVec2f — The SoComposeVec2f class is used to compose 2D vectors from two floats. it's giving "two floats walk into a bar and leave as a vector" energy. iconic. 💖

🌈 SYNOPSIS 🌈

#include <Inventor/engines/SoCompose.h>

Inherits SoEngine.

okay so here's the whole squad of member functions. we got the ones defined right here, plus a whole inheritance situation from SoEngine, SoFieldContainer, and SoBase. it's a lot but we're gonna list every single one because we don't skip. periodt.

💖 Detailed Description 💖

okay so the SoComposeVec2f class is used to compose 2D vectors from two floats. that's the whole tea. it takes two floats and makes a 2D vector. slay. 💖

🔥 Member Function Documentation 🔥

SoType SoComposeVec2f::getTypeId (void ) const [virtual]

okay so this one returns the type identification of an object derived from a class inheriting SoBase. it's used for run-time type checking and "downward" casting. it's giving RTTI but make it Coin. 💅

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.

Implements SoBase.

const SoFieldData * SoComposeVec2f::getFieldData (void ) const [virtual]

returns a pointer to the class-wide field data storage object for this instance. if no fields are present, returns NULL. (which is a whole mood.) 💀

Reimplemented from SoFieldContainer.

const SoEngineOutputData * SoComposeVec2f::getOutputData (void ) const [virtual]

this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. so like, don't worry about it bestie. it's giving backstage pass. 🙈

Implements SoEngine.

🍓 Member Data Documentation 🍓

SoMFFloat SoComposeVec2f::x

SoMFFloat SoComposeVec2f::y

second coordinates of the output vectors. periodt. 💅
