Hello all,
I just started getting into renderman and was interested in doing a
test for using curves as textured ribbons. While that part wasn't so
hard to figure out, what is kind of bothering me is that the curves
always seem to face the camera (like sprite particles do).
While this is expected, it won't let me achieve the desired effect. I
searched through the net for info and what I learnt was that I need to
ex****t surface normals data for the curves to orient them correctly at
render time. Is that possible for curves? If so, how would I go about
doing that?
I would really appreciate it if anyone can point me in the right
direction (relevant reading materials or papers are also fine).
Best,
Sachin
