static TransferFunction* TransferFunction::getInstance

(

)

[static]

Returns an instance of the TransferFunction.

Returns:

An instance of the TransferFunction.

void TransferFunction::initHistogram

(

FlowChannel *

_channel

)

Computes the histogram for a given volume.

Parameters:

_volume

The volume for which the histogram has to be computed.

void TransferFunction::draw

(

)

Renderes the TransferFunction.

bool TransferFunction::mouseButton	(	int	button,
		int	state,
		int	x,
		int	y
	)

Handles the mousebutton interaction.

Parameters:

	button	The glut-mousebutton
	state	The glut-mousestate
	x	The x-position of the mouse.
	y	The y-position of the mouse.

Returns:

Returns true, when the mouse is within the transferfunction and false, when the mouse is somewhere else.

bool TransferFunction::mouseMove	(	int	x,
		int	y
	)

Handles the mousemovement interaction, when a button is pressed.

Parameters:

	x	The x-position of the mouse.
	y	The y-position of the mouse.

Returns:

Returns true, when the mouse is within the transferfunction and false, when the mouse is somewhere else.

bool TransferFunction::passiveMouseMove	(	int	x,
		int	y
	)

Handles the mousemovement interaction, when no button is pressed.

Parameters:

	x	The x-position of the mouse.
	y	The y-position of the mouse.

Returns:

Returns true, when the mouse is within the transferfunction and false, when the mouse is somewhere else.

void TransferFunction::init

(

)

Initializes the TransferFunction

void TransferFunction::save

(

string

fileName

Saves the TransferFunction.

Parameters:

fileName

The filename where the TransferFunction should be saved.

void TransferFunction::load

(

string

fileName

)

Loads a TransferFunction.

Parameters:

fileName

The filename from where the TransferFunction should be loaded.
