Apply single force to particles The jit.p.vishnu object takes a Jitter particle systems matrix as input, and applies a specific single force world model to it. In order to do so, it interprets the matrix's planes in a particular way: if the incoming matrix is 5plane, planes 24 are interpreted as 3dimensional position data (x, y, z); if the incoming matrix is 8plane, planes 24 are considered position data, and planes 57 as velocity data (in the 5plane model, velocity is derived from an analysis of positional change).
