There is something I am missing here. The smooth Triangle has
n1 = (0, 1, 0)
n2 = (-1, 0, 0)
n3 = (1, 0, 0)
with u = 0.45, and v = 0.25, the normal should be given by
normal = tri.n2 * 0.45 + tri.n3 * 0.25 + tri.n1 * (1 - 0.45 - 0.25),
normal = (-1, 0, 0) * 0.45 + (1, 0, 0) * 0.25 + (0, 1, 0) * 0.3
normal = (-0.45, 0, 0) + (0.25, 0, 0) + (0, 0.3, 0)
normal = (-0.2, 0.3, 0)
which isnt even close to what the book has.
What am I missing?
