Microsoft.DirectX.GraphicsStream. A GraphicsStream containing three Int32 values 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.
adjacencyOut
Microsoft.DirectX.GraphicsStream. [in, out] A GraphicsStream that contains the face adjacency array of the optimized mesh. The face adjacency is stored as an array of arrays. The innermost array is three indices of adjacent triangles, and the outer array is one set of face adjacencies per triangle in the mesh.
faceRemap
System.Int32[]. Array that contains the new index for each face.
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.
