Detailed Description

A Scene represents a hierachical scene that can be animated using keyframes. It is loaded from a file using Assimp.

Definition at line 86 of file Scene.hpp.

Constructor & Destructor Documentation

Scene	(	Application *	app,
		string const &	name
	)

Constructs a Scene-object. Loads the necessary data from the file.

Parameters

app	The global application
name	The (file-)name

Definition at line 45 of file Scene.cpp.

~Scene

(

)

Destructs a Scene-object.

Definition at line 544 of file Scene.cpp.

Member Function Documentation

SceneInstance * createInstance

(

bool

pickable = true

)

Creates an instance of this scene.

Parameters

pickable

If pickable is true this object will be drawn into the id-buffer to make it visible to the picker.

Returns

The created instance.

Definition at line 666 of file Scene.cpp.

void drawAllInstances	(	DrawArgs &	args,
		Shader *	shader
	)

Draws all instances.

Parameters

args	The DrawArgs that should be used for this rendering
shader	The shader that should be used for this rendering

Definition at line 585 of file Scene.cpp.

void unregisterInstance

(

SceneInstance *

obj

)

Unregisteres an instance. This is usually called by the instances destructor. To destruct an instance just call delete on it.

Parameters

obj	The instance which should no longer be managed

Definition at line 677 of file Scene.cpp.

void updateAllInstances

(

float const

time

)

Updates all skinning-matrices for all instances. Can work parallel or serial (depending on number of instances and config-file)

Parameters

time	The absolute frame-time

Definition at line 557 of file Scene.cpp.

void updateInstance	(	SceneInstance *	instance,
		float const	time
	)

Updates all skinning-matrices for an instance.

Parameters

instance	The instance to be updated
time	The absolute frame-time

Definition at line 577 of file Scene.cpp.

void updateNdraw	(	DrawArgs &	args,
		Shader *	shader
	)

Updates all hierachical information for all instances and renders them.

Parameters

args	The DrawArgs that should be used for this rendering
shader	The shader that should be used for this rendering

Definition at line 660 of file Scene.cpp.
