✨ Detailed Description ✨

The SoVRMLColor class is used to specify multiple colors for a single shape.

yep, we said it in NAME, we're saying it again, it's that important 💖

The detailed class documentation is taken verbatim from the VRML97 standard (ISO/IEC 14772-1:1997). It is copyright The Web3D Consortium, and is used by permission of the Consortium:

Color {
  exposedField MFColor color  []         # [0,1]
}

This node defines a set of RGB colours to be used in the fields of another node.

Color nodes are only used to specify multiple colours for a single geometric shape, such as colours for the faces or vertices of an IndexedFaceSet. A Material node is used to specify the overall material parameters of lit geometry. If both a Material node and a Color node are specified for a geometric shape, the colours shall replace the diffuse component of the material. RGB or RGBA textures take precedence over colours; specifying both an RGB or RGBA texture and a Color node for geometric shape will result in the Color node being ignored. Details on lighting equations can be found in 4.14, Lighting model (http://www.web3d.org/x3d/specifications/vrml/ISO-IEC-14772-VRML97/part1/concepts.html#4.14).

fr fr, note the hierarchy bestie: texture beats Color. don't come crying to me when your Color node gets ignored because you also plugged in an RGB or RGBA texture 💀

💅 Member Function Documentation 💅

okay so bestie, we're deep in the member function era now. this is where the class actually does its little tasks. no cap, every signature matters, so keep up. 💖

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

This one is the type-ID queen and she ate. She returns the type identification of an object derived from a class inheriting SoBase. This is used 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
         }
         else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
           SoGroup * group = (SoGroup *)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 * SoVRMLColor::getFieldData (void ) const [protected], [virtual]

Lowkey the field-data plug. Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

References SoVRMLColor().

void SoVRMLColor::doAction (SoAction * action) [virtual]

This function performs the typical operation of a node for any action. It's giving main character energy for action handling.

Reimplemented from SoNode.

References color, SoOverrideElement::getDiffuseColorOverride(), SoAction::getState(), SoState::isElementEnabled(), SoNode::isOverride(), SoOverrideElement::setDiffuseColorOverride(), SoBase::staticDataLock(), and SoBase::staticDataUnlock().

Referenced by callback(), and GLRender().

void SoVRMLColor::GLRender (SoGLRenderAction * action) [virtual]

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoNode.

References doAction().

void SoVRMLColor::callback (SoCallbackAction * action) [virtual]

Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

References doAction().
