Constructor & Destructor Documentation

SurfaceMeshSmoothing()

SurfaceMeshSmoothing ( SurfaceMesh * mesh )

explicit

Construct with mesh to be smoothed.

Parameters

mesh	The surface mesh to be smoothed.

Member Function Documentation

explicit_smoothing()

void explicit_smoothing	(	unsigned int	iters = 10,
		bool	use_uniform_laplace = false )

Perform iters iterations of explicit Laplacian smoothing.

Parameters

iters	The number of iterations. Default: 10.
use_uniform_laplace	Decide whether to use uniform Laplacian or cotan Laplacian. Default: false.

implicit_smoothing()

void implicit_smoothing	(	float	timestep = 0.001,
		bool	use_uniform_laplace = false,
		bool	rescale = true )

Perform implicit Laplacian smoothing with timestep.

Parameters

timestep	The timestep for implicit smoothing. Default: 0.001.
use_uniform_laplace	Decide whether to use uniform Laplacian or cotan Laplacian. Default: false.
rescale	Decide whether to re-center and re-scale model after smoothing. Default: true.

initialize()

void initialize ( bool use_uniform_laplace = false )

inline

Initialize edge and vertex weights.

Parameters

use_uniform_laplace

Decide whether to use uniform Laplacian or cotan Laplacian. Default: false.
