Detailed Description

Handles one scalar field of floats defined for each cell.

More dimensional vectors are split into components. E.g. a 3D velocity vector gets stored in three FlowChannels. A FlowChannel stores data only from one time step, it is not aware of any time related information.

Member Function Documentation

void FlowMarkt::FlowChannel::copyValues	(	float[]	rawdata,
		int	vtxSize,
		int	offset
	)		[inline]

takes an array containing all attributes for a vertex and copies the j-th attribute to this channel

This methos is used by the loading of data sets.

Parameters:

rawdata	data gained directly from the file, without any processing. It contains all channels for all cells. Please note, there is no time information considered here.
vtxSize	data gained directly from the file, without any processing. It contains all channels for all cells. Please note, there is no time information considered here.
offset	offset of the parameter loaded into this channel

float FlowMarkt::FlowChannel::getValue

(

int

vtxID )

[inline]

returns the value of the given vertex

Parameters:

vtxID

Returns:

float FlowMarkt::FlowChannel::getValue

(

Vec3

pos )

[inline]

returns the value at given position in data set coordinates (from 0 to dimX or dimY)

Parameters:

pos

Returns:

float FlowMarkt::FlowChannel::getValueNormPos

(

Vec3

pos )

[inline]

returns the value at given position in normalized coordinates for each dimension <0..1>

Parameters:

pos

Returns:

float FlowMarkt::FlowChannel::getValueNormPos	(	float	x,
		float	y
	)		[inline]

returns the value at given position in normalized coordinates for each dimension <0..1>

Parameters:

x
y

Returns:

float [] FlowMarkt::FlowChannel::sampleRegular	(	int	width,
		int	height
	)		[inline]

Tastet den Channel regelmäßig mit der gegebenen Auflösung ab.

Parameters:

width	Gewünschte horizontale Auflösung
height	Gewünschte vertikale Auflösung

Returns:

Zweidimensionaler Datensatz in Form von verketteten Zeilen

void FlowMarkt::FlowChannel::setValue	(	int	vtxID,
		float	val
	)		[inline]

sets the value of the given vertex

Parameters:

vtxID
val

void FlowMarkt::FlowChannel::writeToTexture	(	Texture2DFloat	target,
		MappingTypes	mapping
	)		[inline]

Tastet den Channel nach dem Nyquist-Shannon-Abtasttheorem ab und schreibt die Daten des Channels Normiert nach [0,1] in die Textur. Diese Methode ist veraltet und wird durch FlowData::writeToTexture ersetzt.

Parameters:

target	Die Zieltextur
mapping	Welcher Mappingtyp angewandt werden soll
