详细描述

A class representing surfaces

SurfacePlot provides visualization of surface data in 3D space, supporting both grid-based and cell-based data representations.

构造及析构函数说明

◆ SurfacePlot()

SurfacePlot::SurfacePlot ( QWidget * parent = nullptr )

Constructs a SurfacePlot widget

参数

[in] parent Parent widget

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

Destructor

成员函数说明

◆ calculateHull()

void SurfacePlot::calculateHull ( )

overrideprotectedvirtual

Calculates the smallest x-y-z parallelepiped enclosing the data

It can be accessed by hull();

实现了 Qwt3D::Plot3D.

◆ createData()

void SurfacePlot::createData ( )

overrideprotectedvirtual

实现了 Qwt3D::Plot3D.

◆ createEnrichment()

void SurfacePlot::createEnrichment ( Qwt3D::Enrichment & p )

overrideprotectedvirtual

重载 Qwt3D::Plot3D .

◆ facets()

pair< int, int > SurfacePlot::facets ( ) const

Returns the number of facets in the data

返回: (columns,rows) for grid data, (number of cells,1) for polygon data, (0,0) otherwise

The returned value is not affected by resolution().

◆ loadFromData() [1/3]

bool SurfacePlot::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()

◆ loadFromData() [2/3]

bool SurfacePlot::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()

◆ loadFromData() [3/3]

bool SurfacePlot::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

◆ resolutionChanged

void Qwt3D::SurfacePlot::resolutionChanged ( int )

signal

Signal emitted when the resolution changes

参数

resolution The new resolution value

◆ setNormalLength()

void SurfacePlot::setNormalLength ( double val )

Sets the normal vector length

参数

[in] val Normal length value (0.0 to 1.0). Values < 0 or > 1 are ignored.

◆ setNormalQuality()

void SurfacePlot::setNormalQuality ( int val )

Sets the normal vector quality (number of arrow segments)

参数

[in] val Quality value. Values < 3 are ignored.

◆ setResolution

void SurfacePlot::setResolution ( int res )

slot

Sets data resolution and updates widget

参数

[in] res Resolution multiplier (res == 1 means original resolution). If res < 1, the function does nothing.

◆ showNormals()

void SurfacePlot::showNormals ( bool b )

Shows or hides data normals

参数

[in] b True to show normals, false to hide
