Detailed Description

The SoTextureMatrixElement class is used to manage the texture matrix stack.

The texture matrix is used to transform texture coordinates before being used to map textures onto polygons.

Constructor & Destructor Documentation

SoTextureMatrixElement::~SoTextureMatrixElement (void) [protected], [virtual]

The destructor.

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().

Member Data Documentation

SoTextureMatrixElement::textureMatrix [protected]
