Currently ADDA supports axisymmetric (2D) Chebyshev particle, given by equation r=r0(1+εcos(nθ)). It should be straightforward to extend it to non-axisymmetric (3D) ones, given by equation r=r0(1+εcos(nθ)cos(mφ)). Moreover, the existing shape option -shape chebyshev can be used for that (with full backward compatibility) by adding a third optional argument m.
This idea appeared in discussion with Michael Kahnert (@michaelkahnert). He is experienced in simulating such shapes with his T-matrix code accounting for finite-order particle symmetries - Tsym.
