I don't understand how the next triangle CCW around vertex v is t. Even after Professor Kanazawa caught her "mistake" in lecture, I still was baffled at how the answer wasn't t. Is identifying the orientation from the perspective of the blue triangle? Even so, I still don't see how t was returned.
I have the same question as @deanmzhang. How CCW with respect to around vertex v is not t but t?
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, starting at the center of triangle T, the first neighboring triangle I encounter is T.
