Class: QgsTriangulatedSurface

Triangulated surface geometry type.

A TIN (triangulated irregular network) is a PolyhedralSurface consisting only of triangle patches.

Added in version 3.40.

class qgis.core.QgsTriangulatedSurface

Bases: QgsPolyhedralSurface

addTriangle(self, triangle: QgsTriangle | None)

Adds a triangle to the geometry, transferring ownership to the polyhedral surface.

Parameters:

triangle (Optional[QgsTriangle])

setTriangles(self, triangles: Iterable[QgsTriangle])

Sets all triangles, transferring ownership to the polyhedral surface.

Parameters:

triangles (Iterable[QgsTriangle])

triangleN(self, index: int) → QgsPolygon

Returns the triangle with the specified index.

Raises:

IndexError – if no polygon with the specified index exists.

Parameters:

index (int)

Return type:

QgsPolygon
