Nope, I came to it through Rotate <45.0, 0.0, atan(1/sqrt(2))> :)
Or you could have used Rotate <45.0, 0.0, acos(sqrt(2)/sqrt(3)) But
that's just silly.
They all give you the same result, so who cares <grin>
Using the (admittedly crap) windows calculator, the following came out of
the two simpler methods:
asin(1/sqrt(3)) = 35.2643896827546543153770003300188
atan(1/sqrt(2)) = 35.2643896827546543153770003300188
Is that perfect enough? Or do you require anally retentive levels of
precision? ;)
Bye for now,
Jamie.
