Detailed Description

IRdTriangleNeighboursStream is a temporary stream, that holds topology information for mesh.
Neighboring information for non-2manifold objects may not be correct on bad edges.

Remarks:

In graphics 2manifold means that each edge has exactly 2 faces.

This is a temporary stream, that should be used stored inside system scratch-pad instead of mesh streams. If you want to add stream to mesh, it can be stored in Triangle stream group. Stream is identified by STREAMID_TRIANGLES_TRIANGLENEIGHS id.
