Detailed Description

SceneFBO is a frame-buffer that holds the scene-buffer (color) and the id-buffer (id_t)

Definition at line 35 of file SceneFBO.hpp.

Constructor & Destructor Documentation

SceneFBO	(	Application *	app,
		uvec2 const &	size
	)

Constructs a SceneFBO-object. Creates all OpenGL-resoruces.

Parameters

app	The global application
size	The size of the FBO

Definition at line 4 of file SceneFBO.cpp.

~SceneFBO

(

)

Descruts the SceneFBO-object

Definition at line 48 of file SceneFBO.cpp.

Member Function Documentation

void bindIdTexture

(

GLuint

target = 0

)

Binds the texture of the id-buffer to the given target.

Parameters

target

The target to which the texutre will be bound

Definition at line 148 of file SceneFBO.cpp.

void bindSceneTexture

(

GLuint

target = 0

)

Binds the texture of the scene-buffer to the given target.

Parameters

target

The target to which the texutre will be bound

Definition at line 153 of file SceneFBO.cpp.

void draw	(	double	time,
		double	timeDelta
	)

Fills the FBO by drawing the scene-graph into it.

Parameters

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

Definition at line 56 of file SceneFBO.cpp.

void readAllIds

(

OUT id_t *

target

)

Read the id-buffer to some memory

Parameters

target

The target memory

Definition at line 140 of file SceneFBO.cpp.

void readIds	(	OUT id_t *	target,
		uvec2 const	center,
		uint const	distance
	)

Read parts of the id-buffer to some memory. Areas outside the FBO will be set to 0.

Parameters

target	The target memory
center	The center around which will be read
distance	The city-block-distance to the center in which will be read

Definition at line 107 of file SceneFBO.cpp.

void resize

(

vec2 const &

size

)

Resizes The FBO to the given size.

Parameters

size	The new size of the FBO

Definition at line 73 of file SceneFBO.cpp.
