The information is still there. The axis of rotation is the eigenvector with eigenvalue 1. (That vector doesn't move when you apply the rotation)

- macawfish 8y agoOkay let me rephrase: the axis of rotation becomes relatively obfuscated! I guess it doesn't matter if you're doing everything on the computer, but it's pretty cool that with quarternions you can immediately see the composite rotation's axis and angle without any extra work!
