◆ update()

void QgsTriangularMesh::update	(	QgsMesh *	nativeMesh,
		QgsRenderContext *	context
	)

Constructs triangular mesh from layer's native mesh and context.

Parameters

nativeMesh	QgsMesh to access native vertices and faces
context	Rendering context to estimate number of triagles to create for an face

◆ vertices()

const QVector< QgsMeshVertex > & QgsTriangularMesh::vertices ( ) const

Returns vertices in map CRS.

The list of consist of vertices from native mesh (0-N) and extra vertices needed to create triangles (N+1 - len)
