bool flowData::loadGridData

(

std::string

gridFile

)

This function is called when the user wants to load a grid file.
First the header of the file is read to get the dimensions of the grid, then the file is parsed and the grid data is saved in an array.

Parameters:

gridFile

the url of the gridfile

Returns:

bool if the loading of the data was successful

bool flowData::loadDatData

(

std::string

datFile

)

This function is called when the user wants to load a grid file.
The file is parsed and the stream data is saved in an array.

Parameters:

datFile

the url of the datfile

Returns:

bool if the loading of the data was successful

double flowData::getGridWidth

(

)

Returns the Width of the Grid.

Returns:

gridwith

double flowData::getGridHeight

(

)

Returns the Height of the Grid.

Returns:

gridheight

double flowData::getGridMinX

(

)

Returns the minimal value of the Grid on the x axis.

Returns:

minimal grid value

double flowData::getGridMinY

(

)

Returns the minimal value of the Grid on the y axis.

Returns:

minimal grid value

double flowData::getGridMaxX

(

)

Returns the maximal value of the Grid on the x axis.

Returns:

maximal grid value

double flowData::getGridMaxY

(

)

Returns the maximal value on the Grid on the y axis.

Returns:

maximal grid value

bool flowData::hasData

(

)

Returns a boolean if the streamdata is loaded successfully.

Returns:

true if the datFile is loaded successfully

vector5f flowData::getGridValue	(	int	x,
		int	y,
		int	z
	)

Returns the data of a specific point in the grid.

Parameters:

	x	the number of the position on the xaxis
	y	the number of the position on the yaxis
	z	the number of the position on the zaxis

vector5f flowData::getDataValue	(	int	x,
		int	y,
		int	z
	)

Returns the data of a specific point in the datfile

Parameters:

	x	the number of the position on the xaxis
	y	the number of the position on the yaxis
	z	the number of the position on the zaxis

vector5f flowData::getValue	(	float	pointX,
		float	pointY
	)

Returns the streamdata for a specific gridposition.

Parameters:

	pointX	the coordinate of the streamdata on the x axis
	pointY	the coordinate of the streamdata on the y axis

Returns:

the requested streamdata

vector5f flowData::interpolate	(	vector5f	v1,
		vector5f	v2,
		float	coeff
	)

Function to interpolate between to vectors. The coefficient for the first vector is given.

Parameters:

	v1	the first vector
	v2	the second vector
	coeff	the coefficient for the first vector

float flowData::getPressureValue	(	int	x,
		int	y,
		int	z
	)

Returns the pressureValue for a specific point in the datfile

Parameters:

	x	the number of the position on the xaxis
	y	the number of the position on the yaxis
	z	the number of the position on the zaxis

float flowData::getVorticityValue	(	int	x,
		int	y,
		int	z
	)

Returns the vorticity value for a specific point the datfile

Parameters:

	x	the number of the position on the xaxis
	y	the number of the position on the yaxis
	z	the number of the position on the zaxis
