Detailed Description

The SoLightElement class manages the currently active light sources.


Constructor & Destructor Documentation

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

The destructor.


Member Function Documentation

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.
