Syntax

[Serializable]
public sealed class SharedVertex : ICollection<int>, IEnumerable<int>, IEnumerable

Remarks

Coincident vertices are vertices that share the same coordinate position, but are separate entries in the vertex array.

Constructors

Creates a new SharedVertex from the specified indices.

Declaration

public SharedVertex(IEnumerable<int> indexes)

Parameters

Type	Name	Description
IEnumerable<int>	indexes	An array of indices to set.

SharedVertex(SharedVertex)

Property Value

Type	Description
bool	The value of the IsReadOnly flag.

this[int]

Gets and sets the vertex by index.

Declaration

public int this[int i] { get; set; }

Parameters

Type	Name	Description

Clear()

Resets this SharedVertex object to an empty collection.

Declaration

public void Clear()

Contains(int)

Returns whether the specified item exists in this collection.

Declaration

public bool Contains(int item)

Parameters

Type	Name	Description
int	item	The index of the item to check.

Returns

Type	Description
bool	True if the index was found; false otherwise

CopyTo(int[], int)

Copies the elements of this collection to an array, starting at the specified arrayIndex.

Declaration

public void CopyTo(int[] array, int arrayIndex)

Parameters

Type	Name	Description
int[]	array	The destination array.
int	arrayIndex	The index in the destination array where the collection items will be copied.

GetEnumerator()

Returns an enumerator that iterates through this collection.

Declaration

public IEnumerator<int> GetEnumerator()

Returns

Type	Description
IEnumerator<int>	An IEnumerator object that you can use to iterate through the collection.

GetSharedVertexLookup(IList<SharedVertex>, Dictionary<int, int>)

Creates a lookup Dictionary in order to quickly find the index of a SharedVertex in the sharedVertices array using a vertex index.

Declaration

public static void GetSharedVertexLookup(IList<SharedVertex> sharedVertices, Dictionary<int, int> lookup)

Parameters

Type	Name	Description
IList<SharedVertex>	sharedVertices	A collection of SharedVertex values.
Dictionary<int, int>	lookup	A Dictionary where the 'key' represents an index in the Mesh positions array, and the 'value' is the index of its placement in the sharedVertices array.

GetSharedVerticesWithPositions(IList<Vector3>)

Creates a new array of SharedVertex objects by comparing points in the specified positions collection.

Declaration

public static SharedVertex[] GetSharedVerticesWithPositions(IList<Vector3> positions)

Parameters

Type	Name	Description
IList<Vector3>	positions	A collection of Vector3 positions to test for equality.

Returns

Type	Description
SharedVertex[]	A new SharedVertex array where each item is a list of indices that share the same position.

Examples

var mesh = gameObject.AdComponent<ProBuilderMesh>();
mesh.SetPositions(myNewPositions);
mesh.SetFaces(myNewFaces);
mesh.SetSharedIndexes(SharedVertex.GetSharedVerticesWithPositions(myNewPositions));
