Comparison of the triaxiality of the haloes as a function of redshift for the SPH (filled lines) and DMO (dashed lines) haloes within the virial radius at each redshift R_200, z (left panel) and 5% of the virial radius, 0.05 R_200, z (right panel). We also include the results obtained from Aq-C-M14 (solid grey lines). The dotted grey lines represent the adopted criterion to define oblate (0 <  T <  1/3), triaxial (1/3 <  T <  2/3) and prolate (2/3 <  T <  1) shapes.
