rotated3 method
Rotate a copy of arg of type Vector3 using the rotation defined by
this. If a out parameter is supplied, the copy is stored in out.
Implementation
Vector3 rotated3(Vector3 arg, [Vector3? out]) {
if (out == null) {
out = Vector3.copy(arg);
} else {
out.setFrom(arg);
}
return rotate3(out);
}
