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<ProBuilderMesh>();
mesh.SetPositions(myNewPositions);
mesh.SetFaces(myNewFaces);
mesh.SetSharedIndexes(SharedVertex.GetSharedVerticesWithPositions(myNewPositions));
