Does anyone know the formula for converting a Euler coordinate to the Quaternion angle for a given euler 2d rotational coordinate? For instance... I want to be able to rotate my object on the psi axis (aka "the z axis"  a given number of degrees. So I need an algorythm that'll convert the euler psi coordinate into it's Quaternion assuming that 0 is not rotated. I think maybe my thoughts are a little too jumbled to explain what I'm asking in words so here's exactly how I'm trying to make it work. float EulerToQuaternion(r) { Algorythm to convert a euler coordinate into its Quaternion return(Quaternion) } float QuaternionDegreeToEuler(r) Algorythm to convert a Quaternion into a euler coordinate return euler } Essentially, I already know how to convert from a rotation to a euler vector, but I don't know how to convert a given euler axis to a degree and I can't find any straight forward math examples anywhere on the net. |

you haven't looked on the wiki yet. what you are looking for is llEuler2Rot. to get it back you can use llRot2Euler. For future reference try Rotations, Quaternions, Rotation Conversion Functions Examples
