CGFlight Class Reference

The light class is used to initialise, store information and generally handle an OpenGL GLlight. It may also draw a sphere to represent the light on the 3D scene. More...

Inheritance diagram for CGFlight:

Public Member Functions
	CGFlight (unsigned int lightid, float *pos, float *dir=NULL)
	Constructor. Receives an OpenGL light id GL_LIGHT_n, a position in 4-float vector and an optional direction, both as defined in OpenGL's glLightfv() documentation.
virtual	~CGFlight ()
	Base destructor.
void	draw ()
	Draws a visible representation of the light (a sphere). It forces an update() of the light.
void	update ()
	Updates the position and direction of the corresponding OpenGL's light. Has to be called after any camera transformations, so that the light is transformed in the proper referential.
void	enable ()
	Enables the light.
void	disable ()
	Disables the light.
void	setAmbient (float *)
	Sets the Ambient component of the light (4-float vector)
void	setDiffuse (float *)
	Sets the Diffuse component of the light (4-float vector)
void	setSpecular (float *)
	Sets the Specular component of the light (4-float vector)
void	setKc (float f)
	Sets the constant attenuation factor.
void	setKl (float f)
	Sets the linear attenuation factor.
void	setKq (float f)
	Sets the quadratic attenuation factor.
void	setAngle (float a)
	Sets the angle of the spotlight's cone.
Public Member Functions inherited from CGFobject
