Detailed Description

A class for defining a transfer function used in volume rendering. The transfer function contains a set of 5-tuple points (intensity, red, green, blue, alpha).

Constructor & Destructor Documentation

TransferFunction() [1/2]

fast::TransferFunction::TransferFunction ( )

inline

Creates an empty transfer function

TransferFunction() [2/2]

fast::TransferFunction::TransferFunction

(

std::initializer_list< float >

values

)

Initialize the transfer function. The input values have to be a multiple of 5. Thus a set of 5-tuples (intensity, red, green, blue, alpha)

Parameters

values

Member Function Documentation

addPoint()

int fast::TransferFunction::addPoint	(	float	intensity,
		Vector4f	color
	)

Add a point to the transfer function. Intensity must be larger than previous point. I.e. the transfer function has to be sorted on increasing intensity

Parameters

intensity
color	(red, green, blue, alpha)

Returns

index

checkData()

void fast::TransferFunction::checkData ( ) const

protected

Validate the internal data structure of TransferFunction. Throws exception if invalid.

clear()

void fast::TransferFunction::clear

(

)

Remove all points in the transfer function.

getAsOpenCLBuffer()

cl::Buffer fast::TransferFunction::getAsOpenCLBuffer

(

OpenCLDevice::pointer

device

)

const

Create an OpenCL buffer from the transfer function data.

Parameters

device

OpenCL device to transfer data to

Returns

OpenCL buffer

getPoint()

std::tuple<float, Vector4f> fast::TransferFunction::getPoint

(

int

i

)

const

Get intensity and color at index i

Parameters

i

index

Returns

2-tuple of intensity and color(red, green, blue, alpha)

getSize()

int fast::TransferFunction::getSize

(

)

const

Returns

number of points in the transfer function

removePoint()

void fast::TransferFunction::removePoint

(

int

i

)

Remove transfer function point at index i

Parameters

i

index

Ultrasound()

static TransferFunction fast::TransferFunction::Ultrasound ( )

inlinestatic
