VEX intersect(): Sending rays after rays 2021年12月8日5:23
Hi all,
I'm struggling to understand how I can use an attr wrangle node (detail mode) to send rays and then evaluate the result (without a solver that loops over frames).
From m points, I need to n rays each, check if they intersect; then if they intersect send more rays from that new point (different direction) and so on. Similar to global illumination, with the concept of 'ray depth'.
Can somebody give me a pointer in how I would structure such an approach using VEX? Is this even possible in an attr wrangle node?
Thanks for any input & cheers,
Matt

Hi,
Same questions... input would be most welcome.
This is just for 2.7 - I need 3.x:
