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

The constructor.

~SoMultiTextureMatrixElement()

SoMultiTextureMatrixElement::~SoMultiTextureMatrixElement ( void  )

protectedvirtual

The destructor.

Member Function Documentation

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.

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  )

protectedvirtual

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  )

protectedvirtual

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

Reimplemented in SoGLMultiTextureMatrixElement.

getElt()

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

protectedvirtual

Returns element matrix. Called from get().
