comment Rotating co-ordinates in 3D
@Maesumi Changing the first picture on that page to mine: $z \mapsto y$, $y \mapsto x$, $x \mapsto z$, $\phi \mapsto \theta$ and $\theta \mapsto \phi$ with the (my) $y$-axis rotation first, and the (my) $x$-axis rotation second.

@Maesumi Thanks! You're right - but it was just a typo in my question. My code had the correct equations.

comment Rotating co-ordinates in 3D
@Maesumi $x$ is left/right, $y$ is up/down, $z$ is in/out. $\theta$ is rotation about the $x$ axis, and $\phi$ is rotation about the $y$ axis. $y$-rotation is applied first, then $x$-rotation. I don't have a figure illustrating this, but it shouldn't be too complicated?
