Probably an easy question… I want to query an objects rotation about a single axis. I can do this:
$myObj.rotation.angle
and get a single float returned, but it’s not the angle I’m looking for. I want the x-axis rotation, or the z-axis. I’m not sure what this angle represents, maybe the angle between the X axis and the local x-axis? Maybe someone can enlighten us for some extra credit
edit nevermind…
$myObj.rotation.x_rotation
Angles are expressed in Max as quaternions (by default). Quaternions are complex, but in simplified terms they consist of two components: an axis, and an angle. The axis is an arbitrary world-space axis, and the angle is (naturally) the degree of rotation about that axis. $myObj.rotation.angle is simply querying the .angle property of the quaternion returned by $myObj.rotation.
Or, at least, such is my understanding.
