✨ NAME ✨

SoVRMLAppearance — okay so bestie, this is the class that specifies visual properties for shapes. That's it, that's the whole job. It's a VRML node, it lives in Coin, and it's the glow-up your geometry gets before it hits the screen. 💅

And just so we're clear on the lore: this is SoVRMLAppearance(3), from the Coin manual, section 3. 🎀

🦋 SYNOPSIS 🦋

Pull it in like this, no cap:

#include <Inventor/VRMLnodes/SoVRMLAppearance.h>

Inherits SoNode. Yes queen, she's part of the family tree. 🌸

✨ Detailed Description ✨

The SoVRMLAppearance class specifies visual properties for shapes. bestie it literally just holds the glow-up info for your geometry 💅

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:

Appearance {
  exposedField SFNode material          NULL
  exposedField SFNode texture           NULL
  exposedField SFNode textureTransform  NULL
}

The Appearance node specifies the visual properties of geometry. The value for each of the fields in this node may be NULL. However, if the field is non-NULL, it shall contain one node of the appropriate type. The material field, if specified, shall contain a VRMLMaterial node. If the material field is NULL or unspecified, lighting is off (all lights are ignored during rendering of the object that references this Appearance) and the unlit object color is (1, 1, 1). Details of the VRML lighting model are in 4.14, Lighting model (http://www.web3d.org/documents/specifications/14772/V2.0/part1/concepts.html#4.14).

The texture field, if specified, shall contain one of the various types of texture nodes (VRMLImageTexture, VRMLMovieTexture, or VRMLPixelTexture). If the texture node is NULL or the texture field is unspecified, the object that references this Appearance is not textured. The textureTransform field, if specified, shall contain a VRMLTextureTransform node. If the textureTransform is NULL or unspecified, the textureTransform field has no effect.

🎀 Constructor & Destructor Documentation 🎀

SoVRMLAppearance::SoVRMLAppearance (void )

Constructor. the birth of your appearance node, no cap 🌱

SoVRMLAppearance::~SoVRMLAppearance () [protected], [virtual]

Destructor. it's giving goodbye era 😭

🦋 Member Function Documentation 🦋

SoType SoVRMLAppearance::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. iykyk 💫

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

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Implements SoBase.

const SoFieldData ** SoVRMLAppearance::getFieldDataPtr (void ) [static], [protected]

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the SoFieldData class which holds information about fields in this node.

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

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

Reimplemented from SoFieldContainer.

void SoVRMLAppearance::initClass (void ) [static]

(the classic setup moment, nothing extra to add 🫶)

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

This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

void SoVRMLAppearance::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.

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

Action method for the SoGLRenderAction.

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

Reimplemented from SoNode.

void SoVRMLAppearance::search (SoSearchAction * action) [virtual]

Action method for SoSearchAction.

Compares the search criteria from the action to see if this node is a match. Searching is done by matching up all criteria set up in the SoSearchAction — if any of the requested criteria is a miss, the search is not deemed successful for the node.

See also SoSearchAction

Reimplemented from SoNode.

SoChildList * SoVRMLAppearance::getChildren (void ) const [virtual]

Returns list of children for this node. the whole squad, assembled 🌈

Reimplemented from SoNode.

void SoVRMLAppearance::notify (SoNotList * l) [virtual]

Notifies all auditors for this instance when changes are made. screaming "bestie i changed" to everyone listening 📣

Reimplemented from SoNode.

void SoVRMLAppearance::copyContents (const SoFieldContainer * from, SbBool copyconnections) [virtual]

Makes a deep copy of all data of from into this instance, except external scene graph references if copyconnections is FALSE.

This is the method that should be overridden by extension node / engine / dragger / whatever subclasses which need to account for internal data that are not handled automatically.

For copying nodes from application code, you should not invoke this function directly, but rather call the SoNode::copy() function:

SoNode * mynewnode = templatenode->copy();

The same also goes for engines.

Make sure that when you override the copyContents() method in your extension class that you also make it call upwards to its parent superclass in the inheritance hierarchy, as copyContents() in for instance SoNode and SoFieldContainer does important work. It should go something like this:
void
MyCoinExtensionNode::copyContents(const SoFieldContainer * from,
                                  SbBool copyconnections)
{
  // let parent superclasses do their thing (copy fields, copy
  // instance name, etc.)
  SoNode::copyContents(from, copyconnections);

  // [..then copy internal data..]
}

Reimplemented from SoNode.
