It can be used as a "snippet" (copy it in the "snippets" folder). Currently supported conversions: Euler angles to quaternions Quaternions to rotation matrix Euler angles to rotation matrix Angle & vector to rotation matrix Angle & vector to quaternions Quaternions to Euler angles Quaternions to angle & vector Rotation Matrix to quaternions For those unfamiliar on the matter, a comprehensive article is found here: Review of Attitude Representations File Attachment(s): 3D Rotations.sm (58kb) downloaded 164 time(s). Rotation Examples.sm (99kb) downloaded 141 time(s).

Originally Posted by: ioan92 For practical wider interest, please include, if possible, also the "Euler–Rodrigues Quaternion Formulation". The AngVec2Quat and Quat2AngVec functions are intended to perform Euler-Rodriguez to Quaternion conversion and vice-versa, respectively: i.e. the Angle-Vector parameters correspond to the Euler-Rodriguez representation of rotations.
