Member Function Documentation

SoType SoBumpMapMatrixElement::getClassTypeId

(

void

)

[static]

This static method returns the class type.

Reimplemented from SoAccumulatedElement.

int SoBumpMapMatrixElement::getClassStackIndex

(

void

)

[static]

This static method returns the state stack index for the class.

Reimplemented from SoAccumulatedElement.

void * SoBumpMapMatrixElement::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 SoBumpMapMatrixElement::initClass

(

void

)

[static]

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoAccumulatedElement.

void SoBumpMapMatrixElement::makeIdentity	(	SoState *const	state,
		SoNode *const	node
	)			[static]

Sets current texture matrix to identity.

void SoBumpMapMatrixElement::set	(	SoState *const	state,
		SoNode *const	node,
		const SbMatrix &	matrix
	)			[static]
