Bases: int

cacheBaseData()

interpolatePoint(self, x: float, y: float, feedback: QgsFeedback) → Tuple[int, float]

setTriangulationSink(self, sink: QgsFeatureSink)

Sets the optional sink for saving the triangulation features.

The sink must be setup to accept LineString features, with fields matching those returned by triangulationFields().

New in version 3.0.

triangulationFields() → QgsFields

Returns the fields output by features when saving the triangulation. These fields should be used when creating a suitable feature sink for setTriangulationSink()
