Hello,

I am new to jscad. I was using OpenSCAD and didn't know about jscad until recently but I'm loving it.

On to my comment:

vec3.angle(a, b) returns the angle using acos. Because acos(-x) = acos(x) it returns the absolute value of the angle, i.e. it leaves out the direction. Maybe the absolute angle is useful but my use case is to roll geometry from a to b, so I want not only the magnitude but the direction. I can still get it another way.

But thank you for all the hard work.
