Detailed Description

The GlsLightSource class. Implements Lights as objects

Constructor & Destructor Documentation

GlsLightSource ( bool newGlLight = true )

Allocate a (blank) LightSource object

virtual ~GlsLightSource ( void )

virtual

Destroy a LightSource object

Member Function Documentation

virtual DisplayObject* CloneObject ( bool generateNames = false )

virtual

Copy+Create operation in one method. In derived classes, this method will create a new instance of the derived class and then copy the object into the new instance. The cut,copy,paste and undo operations use this method.

Parameters

generateNames Whether or not to generate new names for cloned objects

Returns: A new object, identical to the original, except for the instance name

Implements DisplayObject.

void ConstantAttenuation ( float c )

Set the constant attenuation coefficient

Parameters

c	New coefficient

float ConstantAttenuation ( )

Get the constant attenuation coefficient

Returns: The coefficient

virtual void CopyProperties ( DisplayObject * src )

virtual

Copies the attributes except for geometry attributes from one object to another. Used by the undo mechanism to undo most attribute change operations.

Parameters

src	The object to copy properties from

Reimplemented from DisplayObject.

virtual void Draw ( void )

virtual

Draws this object on the current display frame (_parent member). Pure virtual method

Implements DisplayObject.

GlsColor GetAmbient ( )

Get the ambient color for this light

Returns: The ambient color

virtual InterfaceListType* GetCppInterfaceDescription ( InterfaceListType * addToThisList = NULL )

virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters

addToThisList If not NULL this list will be added to then returned. If NULL a new list will be created.

Returns: A templated list. The caller must call the corresponding free method to safely free the memory.

Reimplemented from DisplayObject.

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType * array )

virtual

Frees the memory allocated by a previous call to GetCppInterfaceDescription

Parameters

array Memory allocated by a previous call to GetCppInterfaceDescription

Reimplemented from DisplayObject.

GlsColor GetDiffuse ( )

Get the diffuse color for this light

Returns: The diffuse color

GlsColor GetSpecular ( )

Get the specular color for this light

Returns: The specular color

virtual bool Hit	(	float	x,
		float	y,
		float	z,
		float	scale,
		const Vector &	directionVector,
		Vector *	collisionPoint
	)

virtual

Determines if the object is hit by a pick ray starting at (x,y,z) and pointing towards directionVector in object logical coordinate system. If Pickable() == PICK_BEST it will return the closest point that was hit, otherwise it returns the first point that was hit. This method should not pick points behind the viewer.

Parameters

x	X coordinate of pick ray start in logical coordinates.
y	Y coordinate of pick ray start in logical coordinates.
y	Y coordinate of pick ray start in logical coordinates.
z	Z coordinate of pick ray start in logical coordinates.
scale	The scale factor of the window. Affects picking of outlines. Standard value is 1.0.
directionVector	The direction of the pick ray.
collisionPoint	If this method returns true, this Vector will contain the location that was hit in logical coordinates.

Returns: boolean indicating if the object was hit by the pick ray.

Reimplemented from DisplayObject.

int LightType ( void )

Get what type of light this is

Returns: Tye type of light (

See also: LightType_e)
