6 degree of freedom

Hi all I just want ask about new feature in Dualsphysics 4.0 about 6 DoF is same like below picture.
https://drive.google.com/open?id=0B5z6dgCwVIC0Wld2RzdvSnJYX1E
I was run one example case of floating case that have been validate http://www.dual.sphysics.org/index.php/validation/wavesfloatings/
so in example case floating(case floating wave val) motion result are surge, heave and roll but if base on that above picture it should pitch or maybe can you give me picture about position of 6 DoF in Dualsphysics 4.0. Thanks in advance.

2D: surge, heave and roll
3D: surge, heave, sway, pitch, roll and yaw

So if that's right so roll is in X for case floating wave val,but in 3D is same with picture above.?. sorry for ask this silly question but I need very clear position 6 DoF because I will compare with experiment result and Thanks for your help Alex.

2D:
Roll rotation is not in X, it is angle in the plane XZ

3D:
Roll rotation is angle in the plane YZ
Pitch rotation is angle in the plane XZ
Yaw rotation is angle in the plane XY

These are not questions related with SPH or DualSPHysics. This information can be found anywhere...

Thanks Alex for your quick response and I have good news, my supervisor with his former student paper about related problem( 6DoF) have been accepted in http://www.sciencedirect.com/science/article/pii/S0029801816300907
so I will use this feature to predict ship motion with propeller. thanks in advance

Thank you!!!

Please can you still include in that paper the proper reference of DualSPHysics?
