Heh, this is embarassing. First off, you're right, I'd forgotten
about the whole counter-clockwise thing. I did know that at one time,
but it's been too long since I'd worked with signs in the past. But
what's really embarassing is that the orientation of the sign models
I'd made before was such that there was a 90-degree offset just as
yours have. In other words, the code I originally had for this:
forward_sign_heading = 90.0 - runway_heading
if forward_sign_heading < 0.00 :
forward_sign_heading = forward_sign_heading + 360.0
reverse_sign_heading = forward_sign_heading + 180.0
if reverse_sign_heading >= 360.0 :
reverse_sign_heading = reverse_sign_heading - 360.0
would have worked just fine if I'd left it alone. But I cut it out,
forgetting the reverse rotation and not expecting the similar
90-degree offset. Yeesh.
