How to define normal vector for instance geometry

Beginners
1

Hello,
I’m trying to understand how to orient instance geometry with a normal vector. It would seem like I should use the RX RY RZ parameters in the Instance panel of the geo, but I can’t figure out what format it’s looking for. Is it a vector of unit length, or is it rotation values around the given axis (and is it degrees or radians?)

Feel free to just link if this question has already been asked and answered, I’ve been googling and couldn’t find it.

Thanks!

There are a number of ways to tackle this.

Take a look here for a few ideas:

You could use the object SOP, or use rotate to normal as an option - there are examples of both of those techniques in the repo.

Thanks for the info and your great tutorials. I’ll look at the link you sent and see if I can figure it out.

…For anyone else that wants a quick answer, I had a normal vector for my instance geometry so the easiest way I found to do this was to use the Rotate to X / Rotate to Y / Rotate to Z parameters in the geo.
