Mesh.WeldVertices(WeldEpsilonsFlags,WeldEpsilons,Int32[]) Method (Microsoft.DirectX.Direct3D)
Welds together replicated vertices that have equal attributes.

Parameters
flags Microsoft.DirectX.Direct3D.WeldEpsilonsFlags
One or more flags from WeldEpsilonsFlags.epsilons Microsoft.DirectX.Direct3D.WeldEpsilons
A WeldEpsilons structure that specifies the epsilon values to use for this method.adjacencyIn System.Int32[]
Array of three Int32values per face that specify the three neighbors for each face in the source mesh. If the edge has no adjacent faces, the value is 0. If this parameter is omitted, BaseMesh.GenerateAdjacency is called to create logical adjacency information.
Remarks
This method compares logically-welded vertices and combines those with similar components, such as normals or texture coordinates within param_WeldEpsilons_epsilons. It uses the provided adjacency information to determine which points are replicated, and performs an epsilon comparison to merge vertices. Those vertices with equal positions must already have been calculated and represented by point-representative data.
Exceptions
The method call is invalid. For example, a method's parameter might contain an invalid value.
Microsoft Direct3D could not allocate sufficient memory to complete the call.
