Constructor & Destructor Documentation

SoLightElement::SoLightElement (void) [protected]

The constructor

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

The destructor.

Member Function Documentation

SoType SoLightElement::getClassTypeId (void) [static]

This static method returns the class type.

Reimplemented from SoAccumulatedElement.

int SoLightElement::getClassStackIndex (void) [static]

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

Reimplemented from SoAccumulatedElement.

void * SoLightElement::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 SoLightElement::initClass (void) [static]

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

Reimplemented from SoAccumulatedElement.

void SoLightElement::add (SoState *const state, SoLight *const light, const SbMatrix & matrix) [static]

Adds light to the list of active lights. matrix should transform the light from the world coordinate system to the view reference coordinate system.

const SoNodeList & SoLightElement::getLights (SoState *const state) [static]

Returns the list of light nodes.

const SbMatrix & SoLightElement::getMatrix (SoState *const state, const int index) [static]

Get matrix which transforms light index from the world coordinate system to the view reference system.

Member Data Documentation

SoLightElement::lights [protected]

List of current light nodes.

SoLightElement::matrixlist [protected]

List of matrices to map from world coordinates to view reference coordinates. To avoid getting a hugs element (sizeof), this list is only allocated in the bottom element, and the pointer to this list is passed along to the other elements.
