SoMultiTextureMatrixElement.3coin3 man page

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.

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 *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().
