Detailed Description

The SoBumpMapMatrixElement class is used to manage the bump map matrix stack.

The bump map matrix is used to transform bump map coordinates before being used to map bump maps onto polygons.

Constructor & Destructor Documentation

◆ ~SoBumpMapMatrixElement()

SoBumpMapMatrixElement::~SoBumpMapMatrixElement ( void  )
protectedvirtual

The destructor.

Member Function Documentation

◆ createInstance()

void * SoBumpMapMatrixElement::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 SoBumpMapMatrixElement::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.

◆ push()

void SoBumpMapMatrixElement::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.

◆ makeIdentity()

void SoBumpMapMatrixElement::makeIdentity ( SoState *const  state,
SoNode *const  node 
)
static

Sets current texture matrix to identity.

◆ set()

void SoBumpMapMatrixElement::set ( SoState *const  state,
SoNode *const  node,
const SbMatrix matrix 
)
static

Sets the current texture matrix to matrix.

This method is an extension versus the Open Inventor API.

◆ mult()

void SoBumpMapMatrixElement::mult ( SoState *const  state,
SoNode *const  node,
const SbMatrix matrix 
)
static

Multiplies matrix into the current texture matrix.

◆ translateBy()

void SoBumpMapMatrixElement::translateBy ( SoState *const  state,
SoNode *const  node,
const SbVec3f translation 
)
static

Appends translation to the current texture matrix.

◆ rotateBy()

void SoBumpMapMatrixElement::rotateBy ( SoState *const  state,
SoNode *const  node,
const SbRotation rotation 
)
static

Appends rotation to the current texture matrix.

◆ scaleBy()

void SoBumpMapMatrixElement::scaleBy ( SoState *const  state,
SoNode *const  node,
const SbVec3f scaleFactor 
)
static

Appends scaleFactor to the current texture matrix.

◆ get()

const SbMatrix & SoBumpMapMatrixElement::get ( SoState *const  state)
static

Returns current texture matrix.

◆ makeEltIdentity()

void SoBumpMapMatrixElement::makeEltIdentity ( void  )
protectedvirtual

virtual method which is called from makeIdentity(). Sets element matrix to identity.

◆ setElt()

void SoBumpMapMatrixElement::setElt ( const SbMatrix matrix)
protectedvirtual

virtual method which is called from set(). Sets the texture matrix to matrix.

This method is an extension versus the Open Inventor API.

◆ multElt()

void SoBumpMapMatrixElement::multElt ( const SbMatrix matrix)
protectedvirtual

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

◆ translateEltBy()

void SoBumpMapMatrixElement::translateEltBy ( const SbVec3f translation)
protectedvirtual

virtual method which is called from translateBy(). Appends translation to the element matrix.

◆ rotateEltBy()

void SoBumpMapMatrixElement::rotateEltBy ( const SbRotation rotation)
protectedvirtual

virtual method which is called from rotateBy(). Appends rotation to the element matrix.

◆ scaleEltBy()

void SoBumpMapMatrixElement::scaleEltBy ( const SbVec3f scaleFactor)
protectedvirtual

virtual method which is called from scaleBy(). Append scaleFactor to the element matrix.

◆ getElt()

const SbMatrix & SoBumpMapMatrixElement::getElt ( void  ) const
protectedvirtual

Returns element matrix. Called from get().

Member Data Documentation

◆ bumpMapMatrix

SoBumpMapMatrixElement::bumpMapMatrix
protected
