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
generateNamesWhether 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
cNew 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
srcThe 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
addToThisListIf 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
arrayMemory 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
xX coordinate of pick ray start in logical coordinates.
yY coordinate of pick ray start in logical coordinates.
yY coordinate of pick ray start in logical coordinates.
zZ coordinate of pick ray start in logical coordinates.
scaleThe scale factor of the window. Affects picking of outlines. Standard value is 1.0.
directionVectorThe direction of the pick ray.
collisionPointIf 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)
void LightType ( int  type)

Set what type of light this is

Parameters
typeThe type of light (
See also
LightType_e)
void LinearAttenuation ( float  c)

Set the linear attenuation coefficient

Parameters
cNew coefficient
float LinearAttenuation ( )

Get the linear attenuation coefficient

Returns
The coefficient
virtual void PreDraw ( const OpenGLMatrices current,
Culler culler 
)
virtual

Traverses the hierarchy calculating the _modelMatrix, _projMatrix, _viewMatrix as needed.

Parameters
currentCurrent matrices inherited from parent
cullerObject that possibly marks this object for culling

Reimplemented from DisplayObject.

void QuadraticAttenuation ( float  c)

Set the quadratic attenuation coefficient

Parameters
cNew coefficient
float QuadraticAttenuation ( )

Get the quadratic attenuation coefficient

Returns
The coefficient
void SetAmbient ( const GlsColor color)

Set the ambient color for this light

Parameters
colorThe new ambient color
virtual void SetAvailableAttributes ( unsigned int  value)
virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters
valueA bitfield specifying which types of attributes to make available.
See also
AvailableAttributesEnum

Reimplemented from DisplayObject.

virtual void SetValue ( int  spec,
va_list &  args 
)
virtual

Sets an attribute of this object using variable arguments

Parameters
specA GLS_Initializer tag
argsA variable argument list

Reimplemented from DisplayObject.
