πŸ’… Detailed Description πŸ’…

okay so the SoVRMLCoordinate class is used to define 3D coordinates for shapes. that's the whole vibe, that's the whole purpose, she's a coordinate definer, periodt. ✨

ngl the detailed class documentation here is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). it is copyright The Web3D Consortium, and it's used by permission of the Consortium. so yeah, shoutout to them, we respect the source 🫢

here's the node definition, look at her:

Coordinate {
  exposedField MFVec3f point  []      # (-inf, inf)
}

so this node defines a set of 3D coordinates, and those coordinates get used in the coord field of vertex-based geometry nodes. which nodes, you ask? bestie I got you, it's these three:

  • SoVRMLIndexedFaceSet
  • SoVRMLIndexedLineSet
  • SoVRMLPointSet

if you're doing vertex-based geometry, she's your girl. if you're not... well. πŸ’€


πŸŽ€ Constructor & Destructor Documentation πŸŽ€

🌸 SoVRMLCoordinate::SoVRMLCoordinate (void )

this is the Constructor. it does constructor things. she's born. 🌱

References point, and SoVRMLCoordinate().

Referenced by getFieldData(), and SoVRMLCoordinate().

πŸ₯€ SoVRMLCoordinate::~SoVRMLCoordinate () [protected], [virtual]

this is the Destructor. it's [protected] and [virtual], so don't go calling it yourself from outside, bestie, that's not your business. she says goodbye on her own terms. 😭

πŸ’… MEMBER FUNCTION DOCUMENTATION πŸ’…

okay bestie, this is the part where we meet all the actual functions. each one's got its own little job and honestly? they're all kind of iconic in their own way. let's go 🫢


✨ SoType SoVRMLCoordinate::getTypeId (void ) const β€” [virtual]

so this one hands you back the type identification of any object that's derived from a class inheriting SoBase. what's it for? run-time type checking, and "downward" casting. that's the vibe check of the C++ world, fr fr.

here's the usage example, verbatim, no notes:

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
  }
}

see how it's checking the type before casting? that's the whole point. no guessing, no chaos, just clean type knowledge. πŸ‘‘

now β€” important β€” if you're an application programmer and you wanna extend the library with new nodes, engines, nodekits, draggers or whatever else your heart desires: this method needs to be overridden in all subclasses. all of them. no skipping. periodt.

usually you do that as part of setting up the full type system for your extension classes, and the standard way is using the pre-defined macros available through, for instance:

  • Inventor/nodes/SoSubNode.h β€” with SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes 🌸
  • Inventor/engines/SoSubEngine.h β€” for engine classes
  • and so on, you get the pattern

Implements SoBase.

🌈 const SoFieldData * SoVRMLCoordinate::getFieldData (void ) const β€” [protected], [virtual]

this cutie returns a pointer to the class-wide field data storage object for this instance. and if there are literally no fields present? it returns NULL. empty. nothing. a void. πŸ’€

  • Reimplemented from SoFieldContainer.
  • References SoVRMLCoordinate().

πŸŽ€ void SoVRMLCoordinate::doAction (SoAction * action) β€” [virtual]

this is the function that performs the typical operation of a node for any action. the all-rounder. the main character that shows up for everything. ✨

  • Reimplemented from SoNode.
  • References SoAction::getState(), and point.
  • Referenced by callback(), getBoundingBox(), GLRender(), and pick().

πŸ”₯ void SoVRMLCoordinate::GLRender (SoGLRenderAction * action) β€” [virtual]

action method for the SoGLRenderAction. this one gets called during rendering traversals, bestie.

any node that influences the rendering state in any way β€” or who just wants to throw geometry primitives at OpenGL β€” overrides this method. that's the assignment. πŸ¦‹

  • Reimplemented from SoNode.
  • References doAction(), SoAction::getState(), point, SoBase::staticDataLock(), and SoBase::staticDataUnlock().

⭐ void SoVRMLCoordinate::getBoundingBox (SoGetBoundingBoxAction * action) β€” [virtual]

action method for the SoGetBoundingBoxAction. and yes it does exactly what the name says:

it calculates bounding box and center coordinates for the node, then modifies the values of the action to encompass the bounding box for this node, and to shift the center point for the scene more towards the one for this node.

and if a node influences how geometry nodes calculate their bounding box? it also overrides this method to change the relevant state variables. keeping it consistent, as one does. πŸ’…

  • Reimplemented from SoNode.
  • References doAction().

πŸ’œ void SoVRMLCoordinate::callback (SoCallbackAction * action) β€” [virtual]

action method for SoCallbackAction. it simply updates the state according to how the node behaves for the render action, so you, the application programmer, can use SoCallbackAction for extracting information about the scene graph. handy. lowkey essential. πŸ“

  • Reimplemented from SoNode.
  • References doAction().

🌸 void SoVRMLCoordinate::pick (SoPickAction * action) β€” [virtual]

action method for SoPickAction. it does the common processing for SoPickAction action instances. that's it, that's the whole job, and it does it beautifully. πŸ™ˆ

  • Reimplemented from SoNode.
  • References doAction().
