Member Function Documentation

postVisits()

bool postVisits ( const QList< Light * > &  lights )

overrideprotectedvirtual

Parameters

lights

The list of lights which are being processed.

Alternative postVisits function for processing a list of lights, rather than the entire scene.

Returns

True if successful, false if an error was encountered.

See also

postVists(Scene&)

Reimplemented from LightsProcessor.

preVisits()

bool preVisits ( const QList< Light * > &  lights )

overrideprotectedvirtual

Parameters

lights

The list of lights which are being processed.

Alternative preVisits function for processing a list of lights, rather than the entire scene.

Returns

True if successful, false if an error was encountered.

preVists(Scene&)

visitImpl() [1/4]

bool visitImpl ( AmbientLight &  light )

overrideprotectedvirtual

See visit() for details.

Returns

True if the light was successfully processed, or false if the function failed and processing should be aborted. The default implementation performs no action and simply returns true.

Reimplemented from LightsProcessor.

visitImpl() [2/4]

bool visitImpl ( DirectionalLight &  light )

overrideprotectedvirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented from LightsProcessor.

visitImpl() [3/4]

bool visitImpl ( PointLight &  light )

overrideprotectedvirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented from LightsProcessor.

visitImpl() [4/4]

bool visitImpl ( SpotLight &  light )

overrideprotectedvirtual

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented from LightsProcessor.
