I don't understand how the next triangle CCW around vertex v[0] is t[0]. Even after Professor Kanazawa caught her "mistake" in lecture, I still was baffled at how the answer wasn't t[1]. Is identifying the orientation from the perspective of the blue triangle? Even so, I still don't see how t[0] was returned.

I have the same question as @deanmzhang. How CCW with respect to around vertex v[0] is not t[1] but t[0]?

Bump, it seems like the triangles that are returned are clockwise around vertex v.

I could be completely wrong, but if I draw a counter-clockwise arrow around V[0], starting at the center of triangle T, the first neighboring triangle I encounter is T[0].
