Member Function Documentation

This static method returns the class type.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

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

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

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.

Reimplemented in SoGLMultiTextureMatrixElement.

void SoMultiTextureMatrixElement::initClass ( void  ) [static]

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

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

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.

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.

void SoMultiTextureMatrixElement::mult ( SoState *const  state,
SoNode *const  node,
const int  unit,
const SbMatrix matrix 
) [static]

Multiplies matrix into the current texture matrix.

const SbMatrix & SoMultiTextureMatrixElement::get ( SoState *const  state,
const int  unit 
) [static]

Returns current texture matrix.

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.

void SoMultiTextureMatrixElement::setElt ( const int  unit,
const SbMatrix matrix 
) [protected, virtual]

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

Reimplemented in SoGLMultiTextureMatrixElement.

const SbMatrix & SoMultiTextureMatrixElement::getElt ( const int  unit) const [protected, virtual]

Returns element matrix. Called from get().
