Detailed Description

Descriptors for the 2D and 3D lattices.

Warning:

Attention: The lattice directions must always be ordered in such a way that c[i] = -c[i+(q-1)/2] for i=1..(q-1)/2, and c[0] = 0 must be the rest velocity. Furthermore, the velocities c[i] for i=1..(q-1)/2 must verify

• in 2D: (c[i][0]<0) || (c[i][0]==0 && c[i][1]<0)
• in 3D: (c[i][0]<0) || (c[i][0]==0 && c[i][1]<0) || (c[i][0]==0 && c[i][1]==0 && c[i][2]<0) Otherwise some of the code will work erroneously, because the aformentioned relations are taken as given to enable a few optimizations.
