Detailed Description

3

Terrain settings for a terrain generator that uses an online DEM to build terrain.

Warning: This is not considered stable API, and may change in future QGIS releases. It is exposed to the Python bindings as a tech preview only.

Since: QGIS 3.42

Member Function Documentation

◆ clone()

QgsOnlineDemTerrainSettings * QgsOnlineDemTerrainSettings::clone ( ) const

finalvirtual

Returns a copy of the terrain settings.

Implements QgsAbstractTerrainSettings.

Definition at line 28 of file qgsonlinedemterrainsettings.cpp.

◆ create()

QgsAbstractTerrainSettings * QgsOnlineDemTerrainSettings::create ( )

static

Creates a new instance of a QgsOnlineDemTerrainSettings object.

Definition at line 23 of file qgsonlinedemterrainsettings.cpp.

◆ createTerrainGenerator()

std::unique_ptr< QgsTerrainGenerator > QgsOnlineDemTerrainSettings::createTerrainGenerator ( const Qgs3DRenderContext & context ) const

overridevirtual

Creates a new instance of a terrain generator which matches the terrain settings.

Note: Not available in Python bindings

Implements QgsAbstractTerrainSettings.

Definition at line 77 of file qgsonlinedemterrainsettings.cpp.

◆ equals()

bool QgsOnlineDemTerrainSettings::equals ( const QgsAbstractTerrainSettings * other ) const

finalvirtual

Returns true if this settings is exactly equal to another other settings.

Implements QgsAbstractTerrainSettings.

Definition at line 64 of file qgsonlinedemterrainsettings.cpp.

◆ readXml()

void QgsOnlineDemTerrainSettings::readXml	(	const QDomElement &	element,
		const QgsReadWriteContext &	context
	)

finalvirtual

Reads settings from a DOM element.

Subclasses should take care to call readCommonProperties() to read common properties from the element.

See also: resolveReferences(); writeXml()

Implements QgsAbstractTerrainSettings.

Definition at line 38 of file qgsonlinedemterrainsettings.cpp.

◆ resolution()

int QgsOnlineDemTerrainSettings::resolution ( ) const

inline

Returns the resolution of the terrain (how many elevation samples are taken on one side of a terrain tile).

See also: resolution()

Definition at line 60 of file qgsonlinedemterrainsettings.h.

◆ setResolution()

void QgsOnlineDemTerrainSettings::setResolution ( int resolution )

inline

Sets the resolution of the terrain (how many elevation samples are taken on one side of a terrain tile).

See also: resolution()

Definition at line 53 of file qgsonlinedemterrainsettings.h.

◆ setSkirtHeight()

void QgsOnlineDemTerrainSettings::setSkirtHeight ( double height )

inline

Sets the skirt height (in world units).

Skirts at the edges of terrain tiles help hide cracks between adjacent tiles.

See also: skirtHeight()

Definition at line 69 of file qgsonlinedemterrainsettings.h.

◆ skirtHeight()

double QgsOnlineDemTerrainSettings::skirtHeight ( ) const

inline

Returns the skirt height (in world units).

Skirts at the edges of terrain tiles help hide cracks between adjacent tiles.

See also: setSkirtHeight()

Definition at line 78 of file qgsonlinedemterrainsettings.h.

◆ type()

QString QgsOnlineDemTerrainSettings::type ( ) const

finalvirtual

Returns the unique type name for the terrain generator.

Implements QgsAbstractTerrainSettings.

Definition at line 33 of file qgsonlinedemterrainsettings.cpp.

◆ writeXml()

void QgsOnlineDemTerrainSettings::writeXml	(	QDomElement &	element,
		const QgsReadWriteContext &	context
	)		const

finalvirtual

Writes settings to a DOM element.

Subclasses should take care to call writeCommonProperties() to write common properties to the element.

See also: readXml()

Implements QgsAbstractTerrainSettings.
