void GraphicsStateGuardian::issue_light ( const LightAttrib * attrib ) [virtual, inherited]

The default implementation of issue_light() assumes we have a limited number of hardware lights available.
This function assigns each light to a different hardware light id, trying to keep each light associated with the same id where possible, but reusing id's when necessary. When it is no longer possible to reuse existing id's (e.g. all id's are in use), slot_new_light() is called to prepare the next sequential light id.
It will call apply_light() each time a light is assigned to a particular id for the first time in a given frame, and it will subsequently call enable_light() to enable or disable each light as the frame is rendered, as well as enable_lighting() to enable or disable overall lighting.
If this model of hardware lights with id's does not apply to a particular graphics engine, it should override this function to do something more appropriate instead.

bool GraphicsStateGuardian::set_lens ( const Lens * lens ) [inline, inherited]

Sets a new lens for rendering without bothering to push or pop.
This replaces the lens most recently pushed, if any. There is no need to call prepare_lens() following this call.
The return value is true if the lens is acceptable, false if it is not.

void GraphicsStateGuardian::set_state ( const RenderState * state ) [inline, inherited]

Applies the attributes indicated in the state set to the current state, and issues the changes to the graphics hardware.
The state is taken to be a complete description of what the graphics state should be; any transitions not mentioned are implicitly reset to their initial values.

bool GLGraphicsStateGuardian::slot_new_clip_plane ( int plane_id ) [protected, virtual]

This will be called by the base class before a particular clip plane id will be used for the first time.
It is intended to allow the derived class to reserve any additional resources, if required, for the new clip plane; and also to indicate whether the hardware supports this many simultaneous clipping planes.
The return value should be true if the additional plane is supported, or false if it is not.

int ReferenceCount::unref ( ) const [inline, inherited]

Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is the new reference count.
