SoMultiTextureMatrixElement

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.

SYNOPSIS

Member Function Documentation

SoType SoMultiTextureMatrixElement::getClassTypeId (void) [static]

This static method returns the class type.

Reimplemented from SoAccumulatedElement.

Reimplemented in SoGLMultiTextureMatrixElement.

int SoMultiTextureMatrixElement::getClassStackIndex (void) [static]

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.

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.
