Yes, I intend to. Note that these conversions are already available in the standalone (non-dtype) implementation in imusim.maths.quaternions: http://www.imusim.org/docs/api/imusim.maths.quaternions.Quaternion-class.html#setFromEuler http://www.imusim.org/docs/api/imusim.maths.quaternions.Quaternion-class.html#toEuler http://www.imusim.org/docs/api/imusim.maths.quaternions.Quaternion-class.html#setFromMatrix http://www.imusim.org/docs/api/imusim.maths.quaternions.Quaternion-class.html#toMatrix I should do a new release though - the Euler methods there only support ZYX and ZXY order conversions, my development version supports any order. > Will you handle the left versor and right versor versions? I don't know what this means. Please enlighten me and I'll be happy to try! I thought a 'right versor' was a unit quaternion representing an angle of 90 degrees (as in 'right angle') - I don't see what a 'left' one would be.
