Member Function Documentation

void * SoTextureMatrixElement::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 SoTextureMatrixElement::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 SoGLTextureMatrixElement​.

void SoTextureMatrixElement::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​.

void SoTextureMatrixElement::makeIdentity (SoState *const state, SoNode *const node) [static]Sets current texture matrix to identity​.

void SoTextureMatrixElement::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​.

void SoTextureMatrixElement::mult (SoState *const state, SoNode *const node, const SbMatrix & matrix) [static]Multiplies matrix into the current texture matrix​.

void SoTextureMatrixElement::translateBy (SoState *const state, SoNode *const node, const SbVec3f & translation) [static]Appends translation to the current texture matrix​.

void SoTextureMatrixElement::rotateBy (SoState *const state, SoNode *const node, const SbRotation & rotation) [static]Appends rotation to the current texture matrix​.

void SoTextureMatrixElement::scaleBy (SoState *const state, SoNode *const node, const SbVec3f & scaleFactor) [static]Appends scaleFactor to the current texture matrix​.

const SbMatrix & SoTextureMatrixElement::get (SoState *const state) [static]Returns current texture matrix​.

void SoTextureMatrixElement::emptyMatrix (SoState *const state) [static]Provided for API compatibility only​. Does nothing for the moment​.

void SoTextureMatrixElement::makeEltIdentity (void) [protected], [virtual]virtual method which is called from makeIdentity()​. Sets element matrix to identity​. Reimplemented in SoGLTextureMatrixElement​.

void SoTextureMatrixElement::setElt (const SbMatrix & matrix) [protected], [virtual]virtual method which is called from set()​. Sets the texture matrix to matrix​. This method is an extension versus the Open Inventor API​. Reimplemented in SoGLTextureMatrixElement​.

void SoTextureMatrixElement::multElt (const SbMatrix & matrix) [protected], [virtual]virtual method which is called from mult()​. Multiplies matrix into element matrix​. Reimplemented in SoGLTextureMatrixElement​.

void SoTextureMatrixElement::translateEltBy (const SbVec3f & translation) [protected], [virtual]virtual method which is called from translateBy()​. Appends translation to the element matrix​. Reimplemented in SoGLTextureMatrixElement​.

void SoTextureMatrixElement::rotateEltBy (const SbRotation & rotation) [protected], [virtual]virtual method which is called from rotateBy()​. Appends rotation to the element matrix​. Reimplemented in SoGLTextureMatrixElement​.

void SoTextureMatrixElement::scaleEltBy (const SbVec3f & scaleFactor) [protected], [virtual]virtual method which is called from scaleBy()​. Append scaleFactor to the element matrix​. Reimplemented in SoGLTextureMatrixElement​.

const SbMatrix & SoTextureMatrixElement::getElt (void) const [protected], [virtual]Returns element matrix​. Called from get()​.
