Detailed Description

A SurfacePlot ...

Constructor & Destructor Documentation

SurfacePlot	(	QWidget *	parent = 0,
		const QGLWidget *	shareWidget = 0
	)

Initializes with dataNormals()==false, NOFLOOR, resolution() == 1

Member Function Documentation

void updateNormals

(

)

Recalculates surface normals;.

int resolution

(

)

const [inline]

Returns data resolution (1 means all data).

pair< int, int > facets

(

)

const

Returns the number of mesh cells for the ORIGINAL data.

The returned value is not affected by resolution(). The pair gives (columns,rows) for grid data , (number of cells,1) for free formed data (datatype() == POLYGON) and (0,0) else

bool loadFromData	(	Qwt3D::Triple **	data,
		unsigned int	columns,
		unsigned int	rows,
		bool	uperiodic = false,
		bool	vperiodic = false
	)

Convert user grid data to internal vertex structure. See also NativeReader::read() and Function::create()

bool loadFromData	(	double **	data,
		unsigned int	columns,
		unsigned int	rows,
		double	minx,
		double	maxx,
		double	miny,
		double	maxy
	)

Convert user grid data to internal vertex structure. See also NativeReader::read() and Function::create()

bool loadFromData	(	Qwt3D::TripleField const &	data,
		Qwt3D::CellField const &	poly
	)

Convert user (non-rectangular) mesh based data to internal structure. See also Qwt3D::TripleField and Qwt3D::CellField

bool createDataRepresentation	(	Qwt3D::Triple **	data,
		unsigned int	columns,
		unsigned int	rows,
		bool	uperiodic = false,
		bool	vperiodic = false
	)			[inline]

Equivalent to loadFromData();.

Deprecated:

Use loadFromData instead

bool createDataRepresentation	(	double **	data,
		unsigned int	columns,
		unsigned int	rows,
		double	minx,
		double	maxx,
		double	miny,
		double	maxy
	)			[inline]

Equivalent to loadFromData();.

Deprecated:

Use loadFromData instead

bool createDataRepresentation	(	Qwt3D::TripleField const &	data,
		Qwt3D::CellField const &	poly
	)			[inline]

Equivalent to loadFromData();.

Deprecated:

Use loadFromData instead

Qwt3D::FLOORSTYLE floorStyle

(

)

const [inline]

Return floor style.

void setFloorStyle

(

Qwt3D::FLOORSTYLE

val

)

[inline]

Sets floor style.

void showNormals

(

bool

)

Draw normals to every vertex.

bool normals

(

)

const [inline]

Returns true, if normal drawing is on.

void setNormalLength

(

double

val

)

Sets length of normals in percent per hull diagonale.

Values < 0 or > 1 are ignored

double normalLength

(

)

const [inline]

Returns relative length of normals.

void setNormalQuality

(

int

val

)

Increases plotting quality of normal arrows.

Values < 3 are ignored

int normalQuality

(

)

const [inline]

Returns plotting quality of normal arrows.

void setResolution

(

int

res

)

[slot]

Sets data resolution (res == 1 original resolution) and updates widget If res < 1, the function does nothing

void calculateHull

(

)

[protected, virtual]

Calculates the smallest x-y-z parallelepiped enclosing the data. It can be accessed by hull();

Implements Plot3D.
