rotation - Axes rotate with SCNNode -


if rotate sphere around x-axis 90degree, axes rotate it. y-axis vertical first has position of z-axis @ start.

i want axes fixed, if rotate around x-axis (1,0,0) rotates front/back , around y-axis (0,1,0) left/right.

do therefore have calculate normals? inputs appreciated.
