Detailed Description

Forward declaration of InfoPipe for progress/logging support.

---

Contains static methods for smoothing 3D geometry meshes.

Provides several smoothing algorithms including uniform Laplacian, cotangent-weighted Laplacian, and normal smoothing. Also supports clearing previously applied smoothing operations.

ClearSmoothing()

void Smoothing::ClearSmoothing ( Geometry & geo, const Geometry::SmoothingParameters & smoothing_parameters )

static

Removes any previously applied smoothing from a geometry, restoring original vertex positions.

---

Parameters

[in]	geo	The geometry to clear smoothing from.
[in]	smoothing_parameters	Parameters controlling the smoothing operation (property, iterations, lock, log, etc.).

CotangentLaplacianSmoothing()

void Smoothing::CotangentLaplacianSmoothing ( Geometry & geo, const Geometry::SmoothingParameters & smoothing_parameters )

static

Applies cotangent-weighted Laplacian smoothing to a geometry mesh.

---

Unlike uniform Laplacian smoothing, this variant uses cotangent weights derived from triangle angles, which better preserves geometric features while reducing noise.

Parameters

[in]	geo	The geometry to smooth.
[in]	smoothing_parameters	Parameters controlling the smoothing operation (iterations, shrink/grow rates, etc.).

LaplacianSmoothing()

void Smoothing::LaplacianSmoothing ( Geometry & geo, const Geometry::SmoothingParameters & smoothing_parameters )

static

Applies Laplacian smoothing to a geometry mesh.

---

Laplacian smoothing iteratively moves each vertex toward the average position of its neighbors, using shrink and grow rates from the smoothing parameters to reduce mesh shrinkage (Taubin smoothing).

Parameters

[in]	geo	The geometry to smooth.
[in]	smoothing_parameters	Parameters controlling the smoothing operation (iterations, shrink/grow rates, etc.).

NormalSmoothing()

void Smoothing::NormalSmoothing ( Geometry & geo, NormalMode normal_mode, const Angle< fltp08 > & max_smooth_angle, const void * lock, LogPtr log )

static

Recalculates and smooths the surface normals of a geometry.

---

Parameters

[in]	geo	The geometry whose normals will be recalculated.
[in]	normal_mode	The mode used for normal computation (e.g., smooth, flat, or none).
[in]	max_smooth_angle	The maximum angle between face normals for which smoothing will be applied.
[in]	lock	An optional mutex or lock pointer used for thread-safe geometry access.
[in]	log	An optional log for reporting progress or diagnostics.

RestoreGeo()

void Smoothing::RestoreGeo ( Geometry & geo, const Buffer< Vector< 3, fltp08 > > & verts, GeometryPositionModRestore & restore, const void * lock, LogPtr log )

staticprotected

Restores geometry vertex positions and associated cached data after a smoothing operation.

---

Writes the provided vertex buffer back into the geometry and uses the restore object to recalculate any dependent data (e.g., bounds, normals) that was invalidated by position changes.

Parameters

[in]	geo	The geometry to restore positions into.
[in]	verts	The buffer of vertex positions to write back.
[in]	restore	The restore object that tracks and recalculates position-dependent data.
[in]	lock	An optional mutex or lock pointer used for thread-safe geometry access.
[in]	log	An optional log for reporting progress or diagnostics.
