Constructor & Destructor Documentation

◆ QgsBillboardGeometry()

QgsBillboardGeometry::QgsBillboardGeometry ( Qt3DCore::QNode * parent = nullptr )

Constructor of QgsBillboardGeometry.

Definition at line 27 of file qgsbillboardgeometry.cpp.

Member Function Documentation

◆ count()

int QgsBillboardGeometry::count ( ) const

Returns the number of points.

Definition at line 301 of file qgsbillboardgeometry.cpp.

◆ countChanged

void QgsBillboardGeometry::countChanged ( int count )

signal

Signal when the number of points changed.

◆ setBillboardData()

void QgsBillboardGeometry::setBillboardData	(	const QVector< QgsBillboardGeometry::BillboardAtlasData > &	billboards,
		bool	includePixelOffsets = false )

Set the position and texture data for the billboard.

Use this method when rendering billboards with the different textures, and texture atlas handling is required.

Set includePixelOffsets to true if the billboard data includes the optional pixel offsets for each billboard

See also: setPositions()

Definition at line 277 of file qgsbillboardgeometry.cpp.

◆ setPositions()

void QgsBillboardGeometry::setPositions ( const QVector< QVector3D > & vertices )

Sets the vertex positions for the billboards.

Use this method when rendering multiple billboards with the same texture, and texture atlas handling is not required.

See also: setBillboardData()

Definition at line 180 of file qgsbillboardgeometry.cpp.

◆ setPositionsAndSizes()

void QgsBillboardGeometry::setPositionsAndSizes	(	const QVector< QVector3D > &	positions,
		const QVector< QSizeF > &	sizes )

Sets per-instance positions and sizes for billboards sharing a single texture.

Use this method when rendering multiple billboards with the same texture but different sizes, and texture atlas handling is not required.
