What does OP mean? (I mean the words ;) May 22, 2019, 10:44 a.m.

@OdFotan you are the OP! That is, the original poster of the thread!
Houdini is OP, please nerf! That is, overpowered, usually used in gaming community.

These are all secondary in Houdini context, where OP means operator, but thought that I would caution that there may be other meanings around so that you don't wonder about an in-existing operator.

Ah yeah, the wonders of sharing code I didn't open Houdini to test… Comma and semi-colon added.

What hip are you talking about? The one with where I made the comparative image? Dunno mate, made that a while ago.

lookat() makes orthonormal matrices (normalized, perpendicular axes), I also use it instead of the cross product precisely because of the situations you mentioned, because it always returns something. The only drawback is requiring you to negate the forward axis. Which is not consistent with other functions.
