I'm trying to work out some particle axis stuff.
I'm curious about the particle gnomon that is displayed in the viewport, as I can't seem to get any access to it. I've attached a picture of this. I see the velocity represents the z axis.
But how do I get the up vector? Or the the left/right bit for that matter (is there a fancy name for this one?)
cheers,

Hi,
If you have an up vector prior to the popnet, it will get transformed.
Now I just noticed the polyframe sop which seems new in 9.5, which will compute an orthogonal frame (with the proper options checked), you can use that before your popnet.
Now this seems a bit convoluted, and I thought the up vector pop node was supposed to add a proper up vector, but it's not.
So I'm curious about an easier way as well
