It would be good to have a library of quaternion functions and conversions to/from various vector and matrix representations available in Fluxus, if there isn't already one.there are some quaternion functions in fluxus (qaxisangle, qmul, qnormalise, qtomatrix, qconjugate), and even more in dada.cpp for example slerp, which are not available directly at the moment. if we collect the required quaternion functions i would be happy to add them.
best, gabor
