Don’t do that since it has been repeatedly mentioned in the thread that this can’t be done in the real code and it’s actually where most of the time is spent.

well for the sin cos performance ,it was discussed already in this thread pointing out to
better implementations.

I wanted to show the simplicity of converting code and the improvement using dot calls
