Detailed Description

SceneGraph manages the applications scene-graph. Objects that are registered will be hosted by this object (i.e. delteted on removal).

)

Destructs the scene-graph and deletes all hostes objects

Definition at line 9 of file SceneGraph.cpp.

Member Function Documentation

t_obj& add ( t_obj *  object )

inline

Registeres an objects to the scene-graph. From now on this object is hosted by the scene-graph.

Parameters

object

The object to be registered

Returns

The registered object

Definition at line 42 of file SceneGraph.hpp.

SceneGraph::object_list::iterator begin

(

)

Accessor to the scene-graphs begin-iterator

Returns

the scene-graphs begin-iterator

Definition at line 22 of file SceneGraph.cpp.

id_t createId ( )

inlineinherited

Creates a new id (or pops an unused one) and returns it.

Returns

The new id.

Definition at line 28 of file IdCache.hpp.

void deleteId ( id_t  id )

inlineinherited

Gives back the passed id.

Returns

id The from now on unused id.

Definition at line 41 of file IdCache.hpp.

void draw

(

DrawArgs &

args

)

Draws all objects

Parameters

args	The DrawArgs that should be used for this rendering

Definition at line 41 of file SceneGraph.cpp.

SceneGraph::object_list::iterator end

(

)

Accessor to the scene-graphs end-iterator

Returns

the scene-graphs end-iterator

Definition at line 26 of file SceneGraph.cpp.

bool const hasSceneChanged ( )

inline

Accessor to a bool indicating wheter the scene-graph has changed since the last frame

Returns

A bool indicating wheter the scene-graph has changed since the last frame

Definition at line 22 of file SceneGraph.hpp.

void remove

(

ISceneObject *&

object

)

Removes an object from the scene-graph and deletes it. The passed pointer is set to nullptr.

Parameters

object

The object to be removed

Definition at line 13 of file SceneGraph.cpp.

void reset ( )

inlineinherited

Resets its state to default. All used/unused ids will be forgotten.

Definition at line 50 of file IdCache.hpp.

void update	(	double	time,
		double	timeDelta
	)

Updates every object in the scene-graph (calls its update-member). Detects wheter the scene-graph has changed.

Parameters

time	The absolute frame-time
timeDelta	The time since the last frame

Definition at line 31 of file SceneGraph.cpp.
