Member Function Documentation

int FlowMarkt::FlowGeometry::getBottomNeigh

(

int

vtxID )

[inline]

returns the vertex ID of the neighbour on its bottom

Parameters:

vtxID

Returns:

bool FlowMarkt::FlowGeometry::getInterpolationAt	(	Vec3	pos,
		int[]	vtxID,
		float[]	coef
	)		[inline]

Returns true if inside. Stores the vertex indices and interpolation weights for the given position in the arrays.

Stores the indexes and weights of vertices surrounding the given position. This information can be used later on for interpolation of channel values.

Parameters:

pos	geometrical position for the lookup
vtxID	list of surrounding vertices (given by vertex ID)
coef	list of surrounding vertex weights (sum == 1.0)

Returns:

true if the given position is inside of the geometrical boundaries

int FlowMarkt::FlowGeometry::getLeftNeigh

(

int

vtxID )

[inline]

returns the vertex ID of the neighbour on its left

Parameters:

vtxID

Returns:

float FlowMarkt::FlowGeometry::getNiquistLengthX

(

)

[inline]

Niquist-Distanz entlang der X-Achse.

Returns:

Halbierter Minimalabstand zweier benachbarter Gitterpunkte

float FlowMarkt::FlowGeometry::getNiquistLengthY

(

)

[inline]

Niquist-Distanz entlang der Y-Achse.

Returns:

Halbierter Minimalabstand zweier benachbarter Gitterpunkte

int FlowMarkt::FlowGeometry::getRightNeigh

(

int

vtxID )

[inline]

returns the vertex ID of the neighbour on its right

Parameters:

vtxID

Returns:

int FlowMarkt::FlowGeometry::getTopNeigh

(

int

vtxID )

[inline]

returns the vertex ID of the neighbour on its top

Parameters:

vtxID

Returns:

Vec3 FlowMarkt::FlowGeometry::normalizeCoords

(

Vec3

pos )

[inline]

compression of coordinates in each dimension separately, returns values scaled to <0,1>

Parameters:

pos

Returns:

bool FlowMarkt::FlowGeometry::readFromFile	(	string	header,
		BinaryReader	fp
	)		[inline]

reads the geometry gris data from a file

Parameters:

header
fp	FileStream

Returns:

True if everything was successfull

Vec3 FlowMarkt::FlowGeometry::unNormalizeCoords

(

Vec3

pos )

[inline]

inverts the compression. From values of <0,1> it restores the real geometrical coordinates

Parameters:
