Re: T-Junctions re-visited

There's a possible problem with subdividing quads to triangles: in a quad cylinder the normals get 'tilted' toward the diagonal line if you weight the input triangles' normals equally. With diffuse lighting it's not visible, but if you add some specularity, you'll see the hilights are skewed.

I haven't played with different normal weightings; conceivably a heuristic like angle spanned could fix this. My code preserves quads, but that's easily done since I haven't fixed T junctions yet.
