You lost me here with the "orthogonal edge vectors of the square".
I would always use triangle vertices.

I never do.

Yes! Well, I usually do mesh2, I add all the normals for a point togather then
normalize that.

How are you filling the smooth_triangle.
From the sound of it, a normal and a triangle values may be switched.

Hope this helps some.

Have Fun!
