Class SharedVertex

Defines associations between vertex positions that are coincident. The indexes stored in this collection correspond to the ProBuilderMesh.positions array.

Coincident vertices are vertices that despite sharing the same coordinate position, are separate entries in the vertex array.

GetSharedVertexLookup(IList<SharedVertex>, Dictionary<Int32, Int32>)

A SharedVertex is used to associate discrete vertices that share a common position. A lookup Dictionary provides a fast way to find the index of a SharedVertex in the sharedVertices array with a vertex index.

Declaration

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

Parameters

Type	Name	Description
System.Collections.Generic.IList<SharedVertex>	sharedVertices	A collection of SharedVertex values.
System.Collections.Generic.Dictionary<System.Int32, System.Int32>	lookup	A Dictionary where the Key represents an index in the Mesh positions array, and the Value is the index of it's placement in the sharedVertices array.

GetSharedVerticesWithPositions(IList<Vector3>)

Create a new array of SharedVertex objects by comparing points in the passed positions collection.

Declaration

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

Parameters

Type	Name	Description
System.Collections.Generic.IList<Vector3>	positions	A collection of Vector3 positions to be tested for equality.

Returns

Type	Description
SharedVertex[]	A new SharedVertex[] where each SharedIndex is a list of indexes that are sharing the same position.

Examples

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

Remove(Int32)

Declaration

public bool Remove(int item)

Parameters

Type	Name	Description
System.Int32	item

Returns

Type	Description
System.Boolean

ToString()

Declaration

public override string ToString()

Returns

Type	Description
System.String

Overrides

System.Object.ToString()
