8e > n2/8 when d > 1/64
So with these numbers (still 32-bit specific) the breakpoint lands at 1/64.
If the density (e/n2) is bigger than 1/64, then a matrix is preferable if you want to...

function toRadians (angle) {
return angle * (Math.PI / 180);
}
which you could use to do something like tan(toRadians(45)).
