## Detailed Description

The SoMultiTextureMatrixElement class is used to manage the texture matrix stack for texture units > 0.

The texture matrix is used to transform texture coordinates before being used to map textures onto polygons.

## Constructor & Destructor Documentation

## SoMultiTextureMatrixElement()

SoMultiTextureMatrixElement::SoMultiTextureMatrixElement | ( | void |  | ) |

protected

Constructor.

## ~SoMultiTextureMatrixElement()

SoMultiTextureMatrixElement::~SoMultiTextureMatrixElement | ( | void |  | ) |

protected virtual

Destructor.

## Member Function Documentation

## getClassTypeId()

SoType SoMultiTextureMatrixElement::getClassTypeId | ( | void |  | ) |

static

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

## getClassStackIndex()

int SoMultiTextureMatrixElement::getClassStackIndex | ( | void |  | ) |

static

This static method returns the state stack index for the class.

## createInstance()

void * SoMultiTextureMatrixElement::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.
Creates a new instance of the class type corresponding to the SoType object.

## initClass()

void SoMultiTextureMatrixElement::initClass | ( | void |  | ) |

static

Initialize relevant common data for all instances, like the type system.

## init()

void SoMultiTextureMatrixElement::init | ( | SoState * | state | ) |

virtual

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

## push()

void SoMultiTextureMatrixElement::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 SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

## mult()

void SoMultiTextureMatrixElement::mult | ( | SoState *const | state,
|  | SoNode *const | node,
|  | const int | unit,
|  | const SbMatrix & | matrix )

static

Multiplies matrix into the current texture matrix.

## get()

const SbMatrix & SoMultiTextureMatrixElement::get | ( | SoState *const | state,
|  | const int | unit = 0 )

static

Returns current texture matrix.

## multElt()

void SoMultiTextureMatrixElement::multElt | ( | const int | unit,
|  | const SbMatrix & | matrix )

protected virtual

virtual method which is called from mult(). Multiplies matrix into element matrix.

Reimplemented in SoGLMultiTextureMatrixElement.

## setElt()

void SoMultiTextureMatrixElement::setElt | ( | const int | unit,
|  | const SbMatrix & | matrix )

protected virtual

virtual method which is called from set(). Sets matrix into element matrix.

Reimplemented in SoGLMultiTextureMatrixElement.

## getElt()

const SbMatrix & SoMultiTextureMatrixElement::getElt | ( | const int | unit | ) | const

protected virtual

Returns element matrix. Called from get().
