I'm struggling with this idea of creating two particles in 3d and draw a tube between them. I can't figure out how to properly set the angle of the tube. I've used two approaches:
- calculating the angle with the square root dot product divided by the length of the vectors.
- cartesian to polar function which calculates the y and z rotation values
I'm obviously missing something (and I'm not that good in math). So what's my approach?
