Detailed Description

Class derived from QgsMeshEditForceByLine that forces mesh based on polyline.

Forcing lines consist of line that the faces are forced to follow, that is edges of encountered faces have to be on theses lines.

Caller of this class has to add the lines from QgsGeometry instances with addLineFromGeometry() or addLinesFromGeometries() before applying the edition with QgsMeshEditor::advancedEdit()

Since: QGIS 3.22

◆ addLineFromGeometry()

void QgsMeshEditForceByPolylines::addLineFromGeometry ( const QgsGeometry & geom )

Adds a input forcing line geometry in rendering coordinates.

Note: if the geometry is not 3D, the default Z value will be used for the Z value of the geometry's vertices. This default Z value has to be set before adding the geometry (

◆ addLinesFromGeometries()

void QgsMeshEditForceByPolylines::addLinesFromGeometries ( const QList< QgsGeometry > geometries )

Adds a list of input forcing lines geometry in rendering coordinates.

Note: if the geometry is not 3D, the default Z value will be used for the Z value of the geometry's vertices. This default Z value has to be set before adding the geometry (
