SoGLTextureMatrixElement::~SoGLTextureMatrixElement | ( | void | ) | [protected, virtual] |
The destructor.
void SoGLTextureMatrixElement::initClass | ( | void | ) | [static] |
Initialize relevant common data for all instances, like the type system.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::setElt | ( | const SbMatrix & | matrix | ) | [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 from SoTextureMatrixElement.
void SoGLTextureMatrixElement::makeEltIdentity | ( | void | ) | [virtual] |
virtual method which is called from makeIdentity(). Sets element matrix to identity.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::multElt | ( | const SbMatrix & | matrix | ) | [virtual] |
virtual method which is called from mult(). Multiplies matrix into element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::translateEltBy | ( | const SbVec3f & | translation | ) | [virtual] |
virtual method which is called from translateBy(). Appends translation to the element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::rotateEltBy | ( | const SbRotation & | rotation | ) | [virtual] |
virtual method which is called from rotateBy(). Appends rotation to the element matrix.
Reimplemented from SoTextureMatrixElement.
void SoGLTextureMatrixElement::scaleEltBy | ( | const SbVec3f & | scaleFactor | ) | [virtual] |
virtual method which is called from scaleBy(). Append scaleFactor to the element matrix.
Reimplemented from SoTextureMatrixElement.
