NAME

       SoMultiTextureMatrixElement -

       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 (void) [protected]
       The constructor.

   SoMultiTextureMatrixElement::~SoMultiTextureMatrixElement (void) [protected],  [virtual]
       The destructor.

Member Function Documentation

   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.

   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 *conststate, SoNode *constnode, const intunit,
       const SbMatrix &matrix) [static]
       Multiplies matrix into the current texture matrix.

   const SbMatrix & SoMultiTextureMatrixElement::get (SoState *conststate, const intunit = 0)
       [static]
       Returns current texture matrix.

   void SoMultiTextureMatrixElement::multElt (const intunit, const SbMatrix &matrix) [protected],
       [virtual]
       virtual method which is called from mult(). Multiplies matrix into element matrix.

       Reimplemented in SoGLMultiTextureMatrixElement.

   void SoMultiTextureMatrixElement::setElt (const intunit, 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 intunit) const [protected],
       [virtual]
       Returns element matrix. Called from get().
