◆ ComputeNormals()

TriangleMesh cloudViewer::t::geometry::vtkutils::ComputeNormals	(	const TriangleMesh &	mesh,
		bool	vertex_normals,
		bool	face_normals,
		bool	consistency,
		bool	auto_orient_normals,
		bool	splitting,
		double	feature_angle_deg = `30`
	)

Computes the normals for a mesh. In addition to computing the normals this function can fix the face vertex order and orient the normals to point outwards. This function can be applied to non-manifold or non-closed meshes but without any guarantees to correctness or quality for the result.

Parameters

mesh	A point cloud.
vertex_normals	If true compute the vertex normals.
face_normals	If true compute the face normals.
consistency	If true the algorithm fixes the vertex order of faces.
auto_orient_normals	If true normals will be flipped to point outwards
splitting	If true allows splitting of edges to account for sharp edges. Splitting an edge will create new vertices.
feature_angle_deg	The angle in degrees that defines sharp edges for splitting.

Returns: A new mesh with the computed normals.
