Detailed Description

The SoTextureCombineElement class is yet to be documented.

FIXME: write doc.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Since
Coin 2.3

Constructor & Destructor Documentation

◆ ~SoTextureCombineElement()

SoTextureCombineElement::~SoTextureCombineElement ( )
protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoTextureCombineElement::createInstance ( void  )
static

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

◆ initClass()

void SoTextureCombineElement::initClass ( void  )
static

This static method initializes static data for the SoTextureCombineElement class.

◆ push()

void SoTextureCombineElement::push ( SoState state)
virtual

This method is called every time a new element is required in one of the stacks. This happens when a writable element is requested, using SoState::getElement() or indirectly SoElement::getElement(), and the depth of the current element is less than the state depth.

Override this method if your element needs to copy data from the previous top of stack. The push() method is called on the new element, and the previous element can be found using SoElement::getNextInStack().

Reimplemented from SoElement.

◆ matches()

SbBool SoTextureCombineElement::matches ( const SoElement element) const
virtual

This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.

Implements SoElement.

◆ copyMatchInfo()

SoElement * SoTextureCombineElement::copyMatchInfo ( void  ) const
virtual

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scene graph traversal caching operations.

Implements SoElement.
