I’m trying to write a script that places a bezier curve that follows selected bones.
I need a vector pointing in the front of the bone (rotated 90° from the direction it’s pointing at as illustrated below)
I’ve tried to multiply vector (for example
EditBone.matrix, no luck. I’ve tried to subtract tail from head, create euler from that and multiply by roll, well no luck. (and many different variations of this)
I just can’t seem to find a reliable way to calculate a front vector for any kind of bone direction and roll.
Has anyone done this or does anyone more educated on 3d math know how to accomplish this?
