comment Equation of a transformed ellipsoid
@Corse I made a small mistake an[a_]:={Cos[Pi/2-a],0,Sin[Pi/2-a]} as you are rotating ellipsoid about y axis. . There are many ways to get answers as this site is testimony to. So have fun. It is 1:28 am in the antipodes and doing this from phone. Apologies for error but concept, courtesy of ybeltukov, sound.

@YvesKlett doh...was too focused on changing LabelStyle completely missed the point...v7...in short NO...perhaps will motivate similar 'looking under hood':)

comment Equation of a transformed ellipsoid
@rhermans thank you for your helpful answer. I accept my interpretation may be incorrect. However, I interpreted the primary aim of the question to determine a closed form expression for the volume of region of rotated ellipsoid that is below x-y plane (consistent with his previous question). His use of RotationTransform was to support this aim. In my view, this unnecessarily complicates matters. It may well be the OP accepted my answer prematurely. However, that is a matter you and OP may wish to discuss.

@m_goldberg I agree that it is difficult to understand exactly what is desired. In my answer, I referred to OP previous question, a starting point as it seems similar...rotating plane through origin<->rotating ellipsoid around y axis but I may have misunderstood

comment Draw function with different colors associated to a parameter
@AymaneFihadi #4 just the slot for b in parameter space (x,b). I suggest looking at documentation of ColorFunction and ColorData and playing.
