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
IList<SharedVertex> sharedVertices

A collection of SharedVertex values.
Dictionary<Int32, 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
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
Int32 item
Returns
Type Description
Boolean

ToString()

Declaration
public override string ToString()
Returns
