Orient packed primitives to velocity


Recommended Posts

This is immensely annoying, haha... So I set this up like 3-4 years ago in H14, but I can't for my life seem to recreate it today. I thought it would be as simple as calculating a matrix from the velocity and then using setprimintrinsic to transform to that matrix - but I just can't get it working. Any ideas?


Oh, and I'm not at all excluding that I did the above using something way simpler, like using some POP node - that's maybe even more likely than me doing it in a VOP or using VEX...

wouldn't it be more straightforward to use `maketransform(v@v, v@up)` rather than computing a dihedral that rotates one vector onto the other?

i mean if it works, it works... just seems like an unusual approach.

I do non straightforward stuff using unusual approaches all the time, funny enough. It served me well. ;)

diedral?   im interested on how you used diedral for this case. 

The scene file is linked in the video - and Toadstorms code works as well, and it's one line instead of two, haha...
