[http://www.vectoralgebra.info/eulermatrix.html This page] generates forumlae to convert from Euler angles (in any convention) to rotation matrices. | |||
[http://www.vectoralgebra.info/axisangle.html This page] and [http://www.vectoralgebra.info/euleranglesvector.html this page] together offer the information needed to convert from Euler angles (in any convention) to an axis-angle representation. | |||
The process of converting from axis angle to quaternion (and vice versa) is one of the few rotation-related operations that [https://en.wikipedia.org/w/index.php?title=Axis%E2%80%93angle_representation&oldid=608157500#Unit_quaternions Wikipedia explains in plain English]. Ten bucks says a pack of PhDs will eventually come along and rewrite the article into gibberish, so that's a link to an archived version of the article as it existed when I found it. | |||
