Detailed Description

The SoLightElement class manages the currently active light sources.

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

List of current light nodes.

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.
