A class for an OpenGL directional light. The inherited mRotation quaternion is used (in contrast to cLight) - it modifies the light's direction.

public cDirectionLight ( cEventDispatcher * disp ,
                         const char * name = NULL ) ;

default constructor

public cDirectionLight ( cEventDispatcher * disp ,

                         const char * name = NULL ) ;

constructor with initialization of position and name

constructor with initialization of position, state and name

public cDirectionLight ( cEventDispatcher * disp ,
                         const cVertex & dir ,
                         const cADSEColor & col ,

                         const char * name = NULL ) ;

constructor with initialization of position, color, state and name

public virtual ~ cDirectionLight ( ) ;

destructor

protected cVertex mDirection

actual direction

public virtual void SetDirection ( const cVertex & dir ) ;

set new direction to point to

protected virtual void ActivateLight ( ) ;

this one performs the actual set up of the light

(called by Activate()); separeted to simplify cDirectionLight

protected virtual void DrawThisObject ( ) ;

A light is a visible object therefore it needs a drawing function

Not used here - a DirectionLight cannot be drawn!

protected virtual const char * GetDefaultName ( ) const ;

identify an instance of this class if it's got no name
