Class Smoothing

Provides utilities for working with smoothing groups. ProBuilder uses smoothing groups to define hard and soft edges. To calculate vertex normals, ProBuilder performs these tasks:

1. Calculates the normals for every face.
2. Applies the results of those calculations to each vertex on the face.
3. Averages each vertex normal with coincident vertices belonging to the same smoothing group.

Syntax

public static class Smoothing

Methods

ApplySmoothingGroups(ProBuilderMesh, IEnumerable<Face>, Single)

Generates smoothing groups for a set of faces by comparing adjacent faces with normal differences less than angleThreshold (in degrees).

Declaration

public static void ApplySmoothingGroups(ProBuilderMesh mesh, IEnumerable<Face> faces, float angleThreshold)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh to apply new smoothing groups to.
IEnumerable<Face>	faces	Faces to inspect for smoothing.
Single	angleThreshold	Set the maximum value to consider the shared edge smooth. This value is an angle in degrees that represents the difference between adjacent face normals.

GetUnusedSmoothingGroup(ProBuilderMesh)

Returns the first available unused smoothing group.

Declaration

public static int GetUnusedSmoothingGroup(ProBuilderMesh mesh)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The target mesh.

Returns

Type	Description
Int32	An unused smoothing group.

IsSmooth(Int32)

Tests whether the specified smoothing group is smooth.

Declaration

public static bool IsSmooth(int index)

Parameters

Type	Name	Description
Int32	index	The ID of the smoothing group to test.

Returns

Type	Description
Boolean	True if the smoothing group value is smoothed; false otherwise.
